Read with an adult. Take your time. You can say, point, draw or write your answer.
1 Let's look together
A half is one of two equal parts of a whole. Both parts must be the same size.
Fold a paper rectangle so its edges match. Open it. The fold splits it into two equal halves.
Look, point and talk with your adult.
2 Watch how I do it
I share six counters equally between two people. Each gets three. Half of six is three.
3 Your turn
Share ten blocks into two equal parts. What is half of ten?
Have a go before opening the answer.
Let's check together
Five. Two groups of five rebuild ten.
4 Try it away from the page
Fold different paper rectangles into halves. Try a different fold. Check that the parts match.

Adult notes · prerequisites, safety and coverage
Prerequisite: fair sharing. Unequal pieces are not halves. Use shapes, lengths and quantities, not only food pictures.
Use large counters, blocks and paper before symbols. Revisit a lesson until the child can show and explain the idea. Numbers grow from 0–10 to 20, then 100; these pages are not a one-sitting course.
