# Find a pair of cards that make 10, and another, and another……..

Digit Dog and Calculating Cat are finding pairs of digit cards that make 10.

Digit Dog has found two cards that total 10. Calculating Cat is challenging him to find another two cards, 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 cards 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?

Look for learners who:

• are systematic when looking for all the pairs that make 10.
• can explain how they know they have found all the pairs.
• are looking for patterns.
• can organise their work.

What if……….

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