Play hit the button finding halves of numbers to 20.
Find 2 teddies, 2 plates and a basket of objects for halving.
Grab an amount of objects and count how many you have. Can you explore which quantities halve exactly into 2 groups and which will have some left over?
If you have 6, will the teddies have the same?
If you have 5, will the teddies have the same?
Which is an even number? How do you know?
You could draw pictures in your book to show what you have found out.
