1 - Getting Started ~3 mins
Look: five friends are holding up both hands. How many fingers are in the air altogether? Think quietly first, then we will share.
2 - Watch and Notice ~9 mins
Look at the hundred square. Five friends held up both hands — that is five groups of ten. The shaded numbers are 10, 20, 30, 40 and 50.
The figures in a number are called digits. Look at 30: the first digit is 3 and the end digit is 0. When we count in tens, the end digit stays 0. The first digit climbs 1, then 2, then 3.
A group of ten means one full set of ten, like both hands. Seven groups of ten are shaded here. Where did we land?
3 - Try It Together ~8 mins
Your turn as a class. We chant the tens together while one person shades that number on the hundred square. Freeze and say the next ten before each shade: 10, 20, 30 and on.

4 - Write the Tens Line in Your Copy ~4 mins
In your maths copy, write 10, 20, 30, 40, 50, 60, 70, 80, 90 in one careful line.
