Mia counted 17 skips before the rope caught. How far past ten is that?
Here are 16, 17 and 18. Each one is a full ten and some more. The extras are the counters past the full ten. Cover the full ten and name just the extras.
Build 16, then 17, then 18 on the two ten-frames. Each time we say together: ten and ___ makes ___.
In your maths copy, write 16, 17 and 18 in one careful line.
The board shows one number at a time. Build it on the two frames. Keep the full ten still and only add the extras.
