The 4 Noetic Math Contest Topics, With a Strategy for Each
Noetic names four topic areas. What each one looks like on the 20-problem test, the one strategy that matters for it, and an original problem to try.

Noetic Learning says its contest problems “can cover a broad range of mathematics skills taught in school”, and it names four areas: computation and number properties, pattern and algebra, geometry and measurement, and probability and statistics. For each one, here’s what it tends to look like on the 20-problem test, the strategy that wins the most points, and a problem your child can try at the kitchen table.
The four topics in one table
| Topic (Noetic’s wording) | What it looks like on the test | The skill that scores |
|---|---|---|
| Computation and number properties | Money, digits, factors and multiples, remainders, “I’m thinking of a number” | Listing the options in order, then checking the answer |
| Pattern and algebra | Growing patterns, balances, “3 of these and 1 of those”, ages | Spotting the rule, or the difference between two cases |
| Geometry and measurement | Perimeter and area, clocks and calendars, lengths and units | A labeled sketch, and the right unit |
| Probability and statistics | Averages, tables and graphs, “how many ways”, simple chance | Turning the question into a total or a count |
Noetic does not publish how many of the 20 problems fall in each area, so prepare all four. The middle column is our own summary, based on the official topic names and the problems in our grade-by-grade practice sets.
How the test is built
- 20 problems in 45 minutes (50 minutes online), for grades 2 through 8.
- Most answers are a typed number. Noetic says there are “only few multiple-choice problems”; the rest are free response, entered online as a number such as 2, 6.5 or -78.2.
- 5 points per correct answer, no partial credit, under the organizer’s grading instructions for the paper test. Answers must match the key exactly.
- No calculators, no talking, and proctors do not explain questions.
- Two editions. Schools and after-school programs enter teams of up to 30 students from the same grade. Families whose school does not take part use the At-Home edition, which reports a score and national percentile but does not qualify for awards.
Because most problems have no answer choices, your child has to come up with the number from scratch. A method they really understand helps more than a trick they half remember. The last step counts too: if a question asks for hours and your child gives the answer in minutes, it scores zero.
Topic 1: Computation and number properties
Strategy: make an organized list. Many number problems are a small search in disguise. Write the possible numbers in order, test each one against the rule, and stop when one fits. Kids who try this in their heads tend to skip a candidate or test the same one twice.
Try it. A number between 10 and 50 leaves a remainder of 3 when it is divided by 5, and also a remainder of 3 when it is divided by 7. What is the number?
Solution. A remainder of 3 when divided by 5 means the number is 3 more than a multiple of 5: 13, 18, 23, 28, 33, 38, 43, 48. A remainder of 3 when divided by 7 means it is 3 more than a multiple of 7: 10, 17, 24, 31, 38, 45. The only number on both lists is 38. Check: 38 ÷ 5 = 7 remainder 3, and 38 ÷ 7 = 5 remainder 3.
Parent note: the most common wrong answer is 3. It fits both remainder rules, but it isn’t between 10 and 50, so have your child reread the range before answering.
Topic 2: Pattern and algebra
Strategy: compare the two situations and take away what they share. At these grades, algebra shows up as pictures and word problems, not letters. When a problem gives two combinations, line them up and cross out the part they have in common. What’s left is the difference, and that’s usually the key. For a growing pattern, work out how much is added at each step and multiply, rather than counting all the way to the end.
Try it. A box holding 5 identical books weighs 23 pounds. The same box holding only 2 of the books weighs 11 pounds. How many pounds does the empty box weigh?
Solution. Both weighings include the box and 2 books. The first has 3 more books and is 23 − 11 = 12 pounds heavier, so one book weighs 12 ÷ 3 = 4 pounds. Two books weigh 8 pounds, so the empty box weighs 11 − 8 = 3 pounds. Check: 5 × 4 + 3 = 23.
Parent note: children often answer 4, the weight of a book, because it is the first number they find. Ask them to reread the last sentence of the question before writing anything down.
Topic 3: Geometry and measurement
Strategy: draw it, label every length, and put the unit in the answer. Perimeter is the distance all the way around; for a rectangle, area is length × width. Once a sketch has numbers on it, most geometry problems turn into plain arithmetic. Then check the unit (cm, square cm, minutes) before moving on.
Try it. A rectangle is 14 cm long, and its perimeter is 44 cm. A square has the same perimeter as the rectangle. How many square centimeters larger is the area of the square than the area of the rectangle?
Solution. The two long sides use 28 cm, so the two short sides share 44 − 28 = 16 cm: the width is 8 cm. Rectangle area: 14 × 8 = 112 square cm. The square’s side is 44 ÷ 4 = 11 cm, so its area is 121 square cm. The difference is 121 − 112 = 9 square centimeters.
Parent note: the usual slip is forgetting that a perimeter counts each side twice (which gives a width of 44 − 14 = 30 instead of 8), or reporting the square’s area instead of the difference.
Topic 4: Probability and statistics
Strategy: turn it into a total or a count. An average is a total divided by how many there are, so most average problems really ask you to find the total. Chance problems at this level come down to counting the ways, and writing them in a quick list or table stops your child from missing one.
Try it. Five friends have an average of 8 stickers each. Four of them have 5, 7, 9 and 10 stickers. How many stickers does the fifth friend have?
Solution. Five friends averaging 8 means 5 × 8 = 40 stickers in total. The four known friends have 5 + 7 + 9 + 10 = 31. The fifth friend has 40 − 31 = 9 stickers.
Parent note: a child who answers 8 has assumed the fifth friend has exactly the average. The average only tells you about the group’s total, so any one friend can be above or below it.
Four weeks, four topics
Four weeks gives each area a week before the fall contest window opens (dates below). Keep sessions short: about 20 minutes, three or four problems, then talk through the solutions together.
| Week | Focus | What to use |
|---|---|---|
| 1 | Computation and number properties | The free Noetic practice set for your child’s grade, number problems first |
| 2 | Pattern and algebra | The pattern and algebra problems from the set (balances, growing patterns, ratios), and the matching guide chapter |
| 3 | Geometry and measurement | Perimeter, area, time and calendar problems |
| 4 | Probability and statistics, then a timed run | A full 20-problem practice test from the prep guide, timed at 45 minutes |
The free Noetic practice problems give ten original problems per grade, 2 through 6, covering the four areas, with worked solutions. Our Noetic prep guides go further, with a chapter for each problem type and full-length practice tests.
