Preparing for a Math Olympiad: An 8-Week Plan for Primary School Children

Your child does well in math, and the teacher has suggested entering the school or district olympiad. The first question most parents ask is: "How do we prepare?" Many simply start assigning more textbook exercises, but an olympiad tests something different. Below is an honest, practical guide for parents of children in grades 2-4: what makes olympiad problems different, how to build a plan and how to support your child on the day itself.

How an olympiad problem differs from a regular test

A school test checks a topic that has been taught: you learned the rule, now apply it. An olympiad problem usually arrives without a ready-made rule. The child has to find a way in on their own: spot a pattern, try options in an orderly way, or turn the problem into a quick sketch.

That is why a top student can struggle at an olympiad while an average one surprises everyone. Olympiads test four things: logical reasoning, pattern spotting, creative, non-standard thinking and fast, accurate calculation. The last one is often overlooked, yet it is exactly what frees up time for the other three.

Is your child ready? Simple signs

Olympiads are not for everyone. Before you start preparing, look for these signs:

• Schoolwork comes easily and homework does not take long.
• They do not give up on a hard problem at once and can think about it for 5-10 minutes.
• They ask "why does that work?" and enjoy finding answers themselves.
• They like puzzles and logic games.
• Most importantly, they want to take part.

If math makes your child anxious, deal with that first. We cover it in detail in our article on helping a child who is afraid of math.

A 6-8 week preparation plan

As a rough guide, start six to eight weeks before the olympiad. Aim for three or four sessions a week, 25-35 minutes each, with 10 minutes of mental arithmetic on the other days.

1. Weeks 1-2: getting familiar. Three or four easy non-standard problems per session. The goal is curiosity, not correct answers: "so problems like this exist too".
2. Weeks 3-4: problem types. One type per session: patterns today, logic tomorrow. Ask your child to explain the idea of the solution in their own words.
3. Weeks 5-6: mixed sets. Different types shuffled together, so the child has to recognise the type on their own.
4. Weeks 7-8: gentle rehearsal. Once a week, a timed session of 30-40 minutes; on the other days, go over mistakes. The last two or three days are for light practice and rest only.

Do not let sessions clash with school and homework. If the daily routine falls apart, preparation brings fatigue instead of progress.

Problem types with examples

Primary school olympiads usually include four kinds of problems. Here is one example of each:

• Patterns and sequences. 2, 5, 11, 23, ... What comes next? Idea: look for the link between neighbours, not just the difference. Each number is the previous one doubled, plus 1. Answer: 47.
• Logic puzzle. Adam is taller than Ben, and Dan is taller than Adam. Who is the shortest? Idea: draw the three boys on a line in order of height. Answer: Ben.
• Number puzzle. The digits of a two-digit number add up to 9, and swapping the digits makes the number 27 bigger. What is the number? Idea: try the numbers with digit sum 9 in order: 18, 27, 36... Answer: 36 (63 − 36 = 27).
• Spatial reasoning. How many squares are there in a 3×3 grid? Idea: count by size: 9 small ones, 4 of size 2×2 and 1 large one. Answer: 14.

Spotting patterns and missing elements can be practised in a playful way with the number sequence game.

Fast calculation is the foundation

Olympiad time is limited. If a child counts 47 + 38 on their fingers, every check takes a minute and there is no time left to think. A child whose mental arithmetic is automatic can test options quickly, and in number puzzles that makes all the difference.

This is where mental arithmetic helps: it teaches children to picture numbers in their head and carry out steps quickly. See rough benchmarks for each grade in our article on mental math speed by grade, and useful tricks in fast calculation methods. Speed matters, but accuracy matters more: careless mistakes cost a lot of points at an olympiad.

Olympiad day: psychology and stress

Do not tackle new problems the day before. A good night's sleep, a familiar breakfast and leaving home without a rush are the best preparation. Agree on three simple rules in advance:

• Read all the problems first and start with the easiest one.
• If you get stuck, move on and come back later.
• You do not have to solve everything, and that is completely normal at an olympiad.

Phrases like "you must win first place" only add pressure. "Go and see what interesting problems they have" works far better.

Talking about the result, whatever it is

The conversation after the olympiad can matter more than the result itself. Ask about the process, not the score: "Which problem was the most interesting?" Praise effort rather than talent: "you prepared and kept trying right to the end".

If the result is poor, a couple of days later work through one unsolved problem together. If it is great, do exactly the same: it is experience for the next step. An olympiad does not measure a child's worth.

How MentalMath can support preparation

The core of olympiad preparation is solving and discussing problems. But 10-15 minutes a day of mental arithmetic and logic games strengthen the foundation. MentalMath offers mental arithmetic practice and thinking games, including number puzzles such as make 24. They fit nicely into the lighter days of your plan, and for a child they feel like play rather than a lesson.
