Look and say. How many dots?

Do not count one by one. Look at the shape, then write.

How many more to fill the frame?

The full frame is 10. Write the part you can see, then the part that is missing.

The rainbow of ten.

Each arc joins two numbers that make 10. Write the partner at the other end.

0 1 2 3 4 6 7 8 9 10

One pair has no arc, because it joins a number to itself. Which one? 5 and 5.

Move on when

She gives the partner of any number to 10 straight away, without counting up and without looking at a frame. A short pause is fine. Counting on fingers means repeat this session.
