Class 3 Maths: halves, quarters and fair sharing at the dinner table

Ask a seven-year-old to split the last piece of roti with a sibling and watch how seriously they take it. Nobody has to teach them the word "fair". Class 3 simply asks them to turn that instinct into maths: halves, quarters and early division. You don't need to be good at maths for any of it. You need a roti, some paper and about twenty minutes.

The ideas, in plain words

• A half is one of two equal parts of a whole. It's written 1/2.
• A quarter is one of four equal parts of a whole. It's written 1/4, and four quarters make one whole.
• Two quarters make one half. The same amount can go by two names.
• Half and double are opposites. Half of 8 is 4, and double of 4 is 8.
• Fair sharing means everyone gets the same amount. Share 12 mangoes between 2 people and each gets 6. Among 4 people, each gets 3.

Everything hangs on one word, "equal". Cut a roti into two pieces and one is bigger? Neither is a half.

A weekend, four small activities

Fold a half. Give your child a sheet of paper and ask them to fold it so both sides match exactly. Unfold it and point at the crease: "each side is one half." How many halves make the whole sheet? Can they find a different fold that also makes halves?

Fold again. Fold in half, then in half once more. Unfold and count the parts. Ask them to shade one part and tell you how many are left unshaded. Then shade two parts and ask: is this also a half?

Buttons and doubles. Count out 12 buttons or coins. Ask for half, and let your child count out 6. Say "6 is half of 12, and 12 is double of 6." Try 8, then 10. In the car later you can play a quick game: you call a number up to 20, they call back its half or its double.

Hand over the sharing job. Next time there's fruit or a plate of snacks, let your child divide it so everyone gets the same, and tell you how many each person gets. Then the good question: if we shared among 4 instead of 2, does each person get more or less? Plenty of children expect more people to mean more for each. Letting them find out on a real plate is more convincing than being told.

An adult should do any cutting. Paper folding and counting buttons need nothing sharp.

Three questions for dinner

No book needed.

1. If I cut a roti into two pieces and one is bigger, is each piece a half? Why not?
2. How many quarters make a whole? How many make a half?
3. Twelve sweets are shared fairly among 4 children. How many does each child get?

If your child answers in their own words, good. If one question stumbles, that's the one to fold paper for next weekend. Nobody's wrong here, only not finished yet.

The ideas in smaller pieces

The chapter is split into five ideas, each with a short explanation, a "why it matters" line and a two-minute activity: Fair Share, Class 3 Mathematics. The page also lists the quizzes and games that go with each idea.
