Digit Dog is looking for two Numicon® shapes that are equal to the 10 shape. Calculating Cat is challenging him to find another two shapes, and then another two, and then another two.

* Find one example, then another, then another, then one your friend hasn’t found *is a good strategy to encourage learners to use their reasoning skills. Once they have found one pair of shapes challenge them to find another pair, ask:

*Is this pair different?*

*How will you know when you have found all the pairs?*

*How are you going to record your work?*

*Look at the pairs that your friend has found. Are they the same? Different?*

*Are there any shapes you haven’t used? Why?*

Encourage learners to check their pairs by putting them on the 10 shape.

*Can you put your pairs of shapes in order?*

*Why can’t you use the 5 shape?*

*What if……….*

You choose three shapes to total 10? How many ways can you do it?
