Chapter 8 — Fair Share

When one whole is shared equally between 2 people, each share is called a half. Two halves together make one complete whole.

When a whole is shared equally among 4 people, each share is called a quarter. There are 4 quarters in one whole.

Four quarters make one whole. The chapter also shows that 2 quarters are equal to one half.

The chapter uses a story about an old man who gave his two sons a mango tree, a solar lamp, and a woollen blanket. The cunning son Amit proposed an unfair split, and children are asked to think about whether it was truly fair.

Children are asked to take rectangular and square sheets of paper and fold them in half, then explore all the different ways to make a half by folding.

Half and double are opposites of each other. For example, 3 is half of 6 and 6 is double of 3. The chapter uses marbles to practise identifying halves and doubles.

Two halves make one whole. The chapter reinforces this by having children check with physical halves.

Children tick shapes that show quarters, draw lines to divide shapes into quarters, colour given fractions of shapes, and use fraction cards to form a whole.

Yes, the chapter explicitly shows that a shape like a rectangle or square can be folded or divided into halves in different ways, and children are asked to find all the different ways.

Three quarters is three out of four equal parts of a whole. The chapter shows visual examples of 1 quarter, 2 quarters (half), 3 quarters, and 4 quarters (complete whole).

The chapter uses a number line showing 0 to 17 to help children find how far a number is from the double of another number or the half of a number, using marbles as context.

The chapter uses chocolates, parathas, chikki (peanut brittle), mangoes, marbles, flowers, and birds to make the concepts of halves and quarters relatable for Class 3 children.
