We use pictorial representations to explain the fraction half as the quantity obtained by taking 1 part when a whole object is partitioned into two equal parts.

__To make Circles, halves and other fractions:__

*
*

1. Use a compass or a round container / lid to draw 6 (or more) Circles on cardboard:

2. Cut out the Circles:

3. Optional: paint or colour the Circles in different colours:

4. With a ruler, draw the diameter on 1 of the Circles. This is the longest line you can draw between two points on the edge of the circle. If you used a compass, simply draw the line over the small hole that the needle has made:

5. Cut the Circle in half:

6. Take another Circle; cut it in 3 pieces, like this:

7. Take some more Circles, and cut them in 6, 4 and 8 pieces, like this:

8. Leave at least one of the Circles whole:

Make as many sets of Circles as you will need for your lesson. Children could work in groups of 3 or 4, using one set among them.

**There should be one whole Circle for each child.**

__Steps in Teaching:__

1. Show a whole Circle:

2. Show the 2 halves. Place one of the halves on the whole, and demonstrate how the 2 halves together make a whole:

3. Place 2 of the 1/3 pieces on the whole. Ask the children if it is a half?

Place any of the other fractions, and ask the same question.

4. Repeat steps 2 and 3 until all children see and understand what a ‘half’ is.

5. Give each group a set of Circles.

6. The children make halves with the different fraction pieces. They can each use a whole Circle as base:

You can use the same set of Circles to also teach other aspects of Fractions.
