Three ideas about ten

Ten comes just after 9. It is written as 10.
Ten is all the fingers on both your hands together.
Ten is a tidy number — we count in tens later to count big amounts.

Let us try. You have 9 stickers and get one more. How many now?

9 and 1 more is 10. You now have ten stickers!

These pairs make 10: 1+9, 2+8, 3+7, 4+6, 5+5.
If you know one number, you can find its partner to 10.
6 needs 4, 8 needs 2, 3 needs 7. Learn these and adding gets easy!

A ten frame has 10 boxes in two rows of five.
Put a dot in each box; the empty boxes show how many more make 10.
If 7 boxes are filled, 3 are empty, so 7 needs 3 more to make 10.

Remember: the two numbers in a pair can swap and still make 10 — 3+7 and 7+3 both make ten.

Where you'll use it

Tens make life easy

Counting on fingers

Both hands make ten. When you run out of fingers, you have reached 10 — a handy way to keep count.

Fast adding

To add 8 and 5, first make 10 (8 + 2) and then add the 3 left over. Pairs to ten make adding quick.

Packs of ten

Crayons and biscuits often come in tens. Knowing ten helps you see at a glance how many are in a full pack.
