How to Prepare for Math Kangaroo: A Parent's Complete Guide

If your child just signed up for Math Kangaroo, or you are wondering whether they should, this is the guide to start with. Knowing how to prepare for Math Kangaroo comes down to three things: understanding what the test rewards, practicing a little at a time from fall to March, and matching the practice to your child’s level. Below you will find a month-by-month timeline, the skills each level tests, two original problems with worked solutions, and straight answers to the questions parents ask us most, from “Are the free resources enough?” to “Should we sign up for a class?”

One housekeeping note: the contest date, registration windows, and fees change every season, so they live on our Math Kangaroo 2027 page. This guide sticks to what stays the same from year to year.

What is Math Kangaroo?

Math Kangaroo is an international multiple-choice math competition for students in kindergarten through grade 12, held once a year on the third Thursday in March. Children sit a single 75-minute test of puzzle-style problems written by the international Kangaroo committee (AKSF), and in the United States the contest is run by Math Kangaroo USA. It rewards reasoning, careful reading, and spatial thinking far more than speed with school procedures.

It is also big. Math Kangaroo USA reports 60,504 participants at 1,682 centers in 2026. Any student “who can read and work independently at his/her school grade level” can enter, and kindergartners take part at the grade 1 level.

The format in 60 seconds

We cover the format in depth in our Math Kangaroo format guide, so here is only what you need to plan practice. Two details change with the level; the rest is the same for everyone.

Two facts in that table shape everything below. Because questions are grouped by point value, the test gets harder as it goes, so the early questions are the ones to secure, and a child who stalls on a late question should move on and come back. And because a wrong answer costs nothing, no bubble should ever be left blank.

Math Kangaroo levels, awards, and prizes

Levels. The test is shared by two-grade bands: grades 1 and 2 take one test, grades 3 and 4 another, then 5 and 6, 7 and 8, and so on up to 11 and 12. Rankings, though, are by grade. A 3rd grader and a 4th grader answer the same questions, but the 3rd grader is ranked only against other 3rd graders. A younger child’s raw score will often be lower than it will be a year later on the same test, which is worth telling them in advance. Their rank and percentile, though, compare them only with their own grade, so those numbers stay fair.

What every child receives. According to Math Kangaroo USA, each participant gets a mathematical gift, a participation ribbon, and an electronic certificate.

Awards. The top 20 scorers in each grade nationwide are National Winners, with gold, silver, and bronze medals for the top three. The top three scorers in each grade in each state are State Winners and receive blue, red, and white ribbons. Winners receive certificates of ranking and gifts, and top performers are recognized on the Math Kangaroo website in May.

Ranks and percentiles. Students also get a national and a state percentile within their grade. Tied scores share a rank. For most families, the percentile is the most useful number on the report, because it tells you how your child did against same-grade peers.

Honorable mention. Parents search for this a lot, so to be precise: Math Kangaroo USA’s official awards page does not list an honorable mention award or publish criteria for one. If you see honorable mention cutoffs quoted elsewhere, check them against mathkangaroo.org before relying on them.

Is Math Kangaroo worth it?

For most curious kids in grades 1 through 6, we think yes, and the reasons are practical.

• It is low-stakes. One morning, multiple choice, no penalty for guessing, and every participant receives a gift, a ribbon, and a certificate.
• You can enter your own child. There is no need for a school team; in-person, proctored online, and at-home options are listed on our 2027 page.
• It shows kids a different kind of math. Many children who are bored by worksheets light up on problems about folding paper, lying knights, or stacking cubes.
• The percentile is a free check-in. It tells you where your child stands among thousands of same-grade peers nationally, which school report cards rarely do.

It may be a poor fit right now if your child is still building reading fluency (the problems are word-heavy, and in grades 1–2 reading is often the real obstacle), or if timed tests cause real distress. In that case, doing the free sample problems at home with no clock is a gentle way to test the waters. If you are unsure, our readiness checklist by grade walks through the signs.

Math Kangaroo vs Math Olympiad (MOEMS)

“Math Olympiad” usually means MOEMS, the Math Olympiads for Elementary and Middle Schools. The two contests reward similar thinking, but they are built very differently.

Some families do both: MOEMS keeps skills warm all winter, and Math Kangaroo is the spring event. Our MOEMS preparation guide covers that contest in detail.

What is the best way to prepare for Math Kangaroo?

Good preparation comes down to a few principles, and none of them require you to be a math person.

1. Small, steady sessions beat weekend marathons. Three or four problems, about 20 minutes, three or four days a week. That adds up to hundreds of problems by March without burning anyone out.
2. Teach strategies, then practice them. Kangaroo problems are rarely solved by a school procedure. They are solved by drawing a picture, working backwards, trying the answer choices, or spotting a pattern. A child who knows five strategies has a way into almost every problem.
3. Spend more time on mistakes than on new problems. After each session, pick the one problem your child missed and have them explain the right solution back to you. That single habit does more than any worksheet.
4. Save full timed tests for the last six weeks. Early on, time pressure only teaches kids to rush. Late in the season, a few 75-minute run-throughs teach pacing.
5. Practice at the right level. Problems that are far too hard teach a child that they are “bad at this.” Aim for sessions where your child gets most problems right and struggles productively on one or two.

A month-by-month prep timeline

Math Kangaroo is always in March, so this plan works in any year. If you are starting late, join the timeline wherever you are and skip ahead; even six weeks of focused practice makes a visible difference.

For practice material, our free Math Kangaroo practice questions by grade and the practice posts for grades 1–2, grades 3–4, and grades 5–6 are all original problems with full solutions.

Math Kangaroo skills and difficulty by level

Math Kangaroo does not follow a school curriculum, but the official Math Kangaroo USA class descriptions give a good picture of what each level draws on. The difficulty notes below are our own read of the contest.

Grades 1–2

Skills: counting and number patterns, place value, addition and subtraction strategies, 2D and 3D shapes, telling time and calendars, money, simple fractions, measurement, graphs, and early logical thinking.

Difficulty: the math itself rarely goes past what a 2nd grader knows. What makes it hard is reading a short story problem carefully, holding two conditions in mind at once, and picturing shapes from different sides. At this level many “math” mistakes are reading mistakes.

Tip: read problems aloud together at first, then have your child read them to you. Keep a box of blocks nearby for 3D questions.

Our Math Kangaroo guide for Grades 1–2 is written for this age, with problems pitched at the right level and kid-friendly, step-by-step solutions.

Grades 3–4

Skills: multi-step story problems, the four operations, fractions, geometry, symmetry, spatial reasoning (rotations and different perspectives), and logical deduction.

Difficulty: this is the level where problems start having two or three steps, and where logic puzzles (who is lying, who sits where) show up regularly. Third graders often find the 5-point problems hard because they require organizing information, which is a skill school hasn’t asked of them yet.

Tip: teach your child to make a small table or list whenever a problem has several people or conditions. It turns a confusing paragraph into something they can check.

Our Math Kangaroo guide for Grades 3–4 builds those habits topic by topic.

Grades 5–6

Skills: number sense, fractions, algebraic thinking, logical reasoning, geometry, and mental visualization. The official class for this level also works on ratios and diagrams, proportionality, multiples, divisors and remainders, digit problems, area and perimeter, and geometric transformations.

Difficulty: the jump here is real. The test goes from 24 to 30 questions in the same 75 minutes, which is about 2.5 minutes per question instead of about 3. Problems lean more on number theory (remainders, divisibility) and on area and angle questions that need a clever cut or rearrangement rather than a formula.

Tip: pacing matters now. In February, practice doing the 3-point questions briskly so there is time left for the last ten.

Our Math Kangaroo guide for Grades 5–6 covers these topics with strategy lessons and a full practice test.

Grades 7–8

Skills: number theory, fractions and decimals, ratios and proportions, algebra, and geometry, applied in non-routine settings.

Difficulty: problems often combine two areas, such as an equation hidden inside a geometry picture, and the 5-point questions reward students who can set up a problem cleanly before computing anything.

Tip: have your child write a one-line plan before calculating. Many lost points at this level come from correct arithmetic on a misread setup.

Our Math Kangaroo guide for Grades 7–8 is aimed at middle schoolers who want competition-level work beyond school math.

Two original practice problems

These are original problems written in the Kangaroo style, not taken from any real test. Let your child try each one before reading the solution.

Problem 1 (Grades 3–4 style, 4 points): The Sticker Swap

Sam gave half of his stickers to his sister. Then he gave 3 more stickers to his friend. Now Sam has 7 stickers left.

How many stickers did Sam have at the start?

(A) 14   (B) 17   (C) 20   (D) 23   (E) 26

Answer: (C) 20.

Solution (work backwards). Undo each step, starting from the end.

• Sam ends with 7. Before he gave 3 to his friend, he had 7 + 3 = 10.
• Those 10 stickers were the half he kept after giving half to his sister, so at the start he had 10 × 2 = 20.

Check: half of 20 is 10, and 10 − 3 = 7. ✓

Why it matters: a child who tries to go forwards has to guess a starting number. Working backwards turns the problem into two easy steps. You can also teach your child to test the answer choices: starting from (A) 14 gives 7 − 3 = 4, too few, so move up.

Problem 2 (Grades 5–6 style, 5 points): The Two Remainders

How many whole numbers from 1 to 100 leave a remainder of 2 when divided by 3 and a remainder of 2 when divided by 4?

(A) 7   (B) 8   (C) 9   (D) 10   (E) 12

Answer: (C) 9.

Solution. If a number leaves remainder 2 when divided by 3, then the number minus 2 is a multiple of 3. If it also leaves remainder 2 when divided by 4, the number minus 2 is a multiple of 4 as well. A number that is a multiple of both 3 and 4 is a multiple of 12.

So the numbers we want are 2 more than a multiple of 12: 2, 14, 26, 38, 50, 62, 74, 86, 98. The next one, 110, is too big. That is 9 numbers.

Check: 50 ÷ 3 = 16 remainder 2, and 50 ÷ 4 = 12 remainder 2. ✓

Why it matters: listing every number from 1 to 100 would take the whole 2.5 minutes. Spotting that “same remainder” means “subtract it and look for a common multiple” solves it in under a minute, and that shortcut comes up again and again at this level.

Problem-solving strategies to teach before test day

Most Kangaroo problems give way to one of a handful of strategies. Name them out loud with your child so they become tools they reach for.

• Draw it. Paths, folds, and “how many squares” questions get much easier on paper. Scratch paper is allowed.
• Work backwards when a problem gives you the ending and asks for the start, like the sticker problem.
• Make a table or list for logic puzzles and counting problems, so nothing is counted twice or missed.
• Try the answer choices. With five options, plugging them in is often faster than solving from scratch.
• Eliminate. Crossing out two impossible choices turns a blind guess into a one-in-three chance.
• Skip and return. Circle a problem that isn’t clicking, move on, and come back with fresh eyes.
• Fill every answer. Nothing is taken away for a wrong answer, so in the last two minutes every blank gets a guess.

Are free Math Kangaroo resources enough?

Here is exactly what Math Kangaroo USA offers for free, as of September 2026:

• Sample questions from 2006 to 2026, three per level each year (one each at 3, 4, and 5 points), with answers.
• Answer keys (letters only) for every test from 1998 to 2026.
• Two full past tests in PDF (2015 and 2025) and two online practice tests (2010 and 2020) for each level from grades 1–2 through 7–8.
• Video solutions to past exams, free to registered students with the code on their registration page.

Everything else from the official site, including most past tests, the written solutions, and the books of past problems, is paid.

So are the free resources enough? For a first-time participant who mostly wants to enjoy the day, yes. The sample questions and four free full tests give your child a clear feel for the style, and the videos help once you have registered. Where free material runs short is explanation and volume by topic. An answer key tells you a child got question 18 wrong; it doesn’t teach them how to approach that kind of problem next time. If your child wants to improve their percentile, you will want either more worked solutions or a structured resource that teaches strategies topic by topic.

Free sources you can add from us: the practice questions by grade, the practice-problem posts linked above, and the Problem of the Week, one original problem in your inbox every Monday.

Should my child self-study or take a Math Kangaroo class?

Both work. The right choice depends more on your child than on the contest.

Self-study at home tends to work well when:

• Your child likes puzzles and will sit with a problem for a few minutes before asking for help.
• You (or an older sibling) can spend 15–20 minutes a few times a week going over mistakes, even if you aren’t a math person. You don’t need to know the answer; you need to ask “How did you get that?”
• You have a resource with full worked solutions, so neither of you is stuck when a problem doesn’t click.

A class tends to help when:

• Your child learns better with peers or finds it easier to take direction from someone who isn’t a parent.
• Your child is aiming for a top state or national rank and needs regular exposure to the hardest problems.
• Your schedule makes consistent home practice unrealistic.

Math Kangaroo USA runs its own online classes for grades 1–8: 10 one-hour sessions with up to 12 students, grouped by level. It also states on its classes page that it does not authorize or endorse third parties to run classes on its behalf, so any other class is independent of the contest organizer.

A mix is common too: self-study through the fall, then a short class or a few timed practice tests in February.

What is the best online Math Kangaroo course for each grade?

We won’t rank other companies’ courses, and there is no single best one for every child. What we can do is tell you what to look for, because the same checklist works at every grade:

• Taught at your child’s level. A class for “grades 3–6” is two different tests. Look for classes built for one two-grade band.
• Clear about where problems come from. Past contest problems are published by Math Kangaroo USA, so ask whether a course writes its own practice problems or works from past tests you could also get directly.
• Strategy teaching. Ask what a typical session looks like. You want most of the hour spent on how to approach problems, with the answer key as the last step.
• Small groups. Your child should be able to explain their thinking out loud at least once per session.
• Homework with solutions. Practice between sessions, with worked solutions, is where most of the learning happens.
• A schedule that ends before March. The best time for a course is fall through February, leaving the final weeks for timed practice.
• A trial or sample lesson. Any good program should let you see a lesson or sample materials before you pay.

If a self-paced resource fits your family better than a live class, our grade-by-grade Math Kangaroo prep guides follow the same principles: one guide per level, original problems, strategy chapters, and a full practice test with step-by-step solutions.

Common prep mistakes

• Starting with full timed tests. A 5-point problem in October, under a clock, mostly teaches frustration. Build up to the timer.
• Practicing only easy problems. Confidence matters, but the 4- and 5-point problems are where scores separate. Include one stretch problem in every session.
• Skipping the review. Doing 30 new problems teaches less than fully understanding the 3 your child missed.
• Leaving answers blank. With no penalty, a blank answer throws away points. Practice the habit of guessing in the final minutes.
• Comparing across grades. A 3rd grader and a 4th grader take the same test but are ranked separately. Compare your child to their own last attempt.

The week before and contest day

• The week before: light review only, a couple of favorite problems, regular sleep.
• Arrive early: Math Kangaroo asks students to arrive at least 15 minutes before the assigned start time.
• Leave devices at home: calculators, phones, smartwatches, and other electronic devices are not allowed. Pencils and erasers are fine, and scratch paper is provided in person.
• For online testing: the 75 minutes start when the student clicks the start button, and the camera stays on so the proctor can see them.
• There is no make-up test for in-person or online students, so plan around the date early.
• Afterwards: celebrate the effort before the score. Results and percentiles come later, and they are more useful as a starting point for next year than as a verdict.

Frequently asked questions

What is Math Kangaroo? An international multiple-choice math competition for K–12 students, held every year on the third Thursday in March. Students solve 24 (grades 1–4) or 30 (grades 5–12) puzzle-style problems in 75 minutes.

How far ahead should we start preparing? Starting in the fall gives you a relaxed pace. Six to eight weeks of steady practice still helps a lot if you are starting in winter.

How much practice per week? We suggest three or four sessions of about 20 minutes, with three or four problems each, plus one weekly timed test in February.

Are free Math Kangaroo resources enough? For a first-timer, yes: official sample questions, answer keys, and four free full tests per level cover the style. For a child aiming at a higher percentile, you will want more worked solutions organized by topic.

Should my child self-study or take a class? Self-study works well for independent, puzzle-loving kids with a parent who can review mistakes. A class helps kids who learn best with peers or who are aiming for top ranks.

Is Math Kangaroo harder than school math? The math content is close to grade level, but the problems are less routine. Expect even strong students to find the 5-point questions hard; that is how the test is designed.

What happens after Math Kangaroo? Many kids keep going with other contests. For middle schoolers, our AMC 8 parent’s guide covers the next common step, and our list of the best math competitions for 6th graders shows other options.

Where to go from here

If you haven’t registered yet, start with the Math Kangaroo 2027 dates and fees, since the early registration price doesn’t last all season. Then pick your child’s level: the Grades 1–2, Grades 3–4, Grades 5–6, or Grades 7–8 guide gives you a ready-made plan from now until March. Whichever route you choose, three or four problems at the kitchen table this week is a good start.
