1 - Getting Started ~3 mins
One pizza, two hungry friends. How do we share it so it is fair, so nobody grumbles?
2 - Watch and Notice ~7 mins
Watch two fair shares. Each whole is cut into two equal parts. One of those parts is called a half.
Look carefully: do the two parts match?
3 - Try It Together ~9 mins
We cut a whole into two matching parts on the board. Everyone checks: do both parts match before we call one part a half?
Cut a fair half
4 - Draw a Half in Your Copy ~2 mins
In your maths copy, draw a circle. Then draw one straight line through the middle so it is cut into two halves.
5 - Class Challenge ~7 mins
Make a fair half on the board. Each time ask: are the two parts exactly the same?
