Two original practice olympiads, one for Division E and one for Division M: five problems each, a 30-minute clock, and solutions that name the strategy behind every answer.
Sixth grade is when the elementary and middle-school contest lists overlap: MATHCOUNTS opens, MOEMS lets your child compete in either division, and every 5th-grade contest is still open. Here is how to pick one.
The seven contests open to a 4th grader are still the menu in 5th grade, and the level steps up: a longer Math Kangaroo paper, the core of MOEMS Division E, and middle school one year away. Here is how to pick one.
MOEMS is five problems a month, November through March, and that shape changes how you prepare. Here's the format, the scoring, how to enter when your school doesn't run it, this season's dates and fees, and three original problems with solutions.
Fourth grade is the year the list of math competitions roughly doubles — MOEMS, Math League, and MathCON all open up. Here's the full menu of seven, and how to pick one without signing up for all of them.
A simple decision guide for parents: pick the right elementary math competition by your child's grade, personality, and how your school works — in about five minutes.
