Lesson Details

Key learning points

Partition one of the addends to make a pair that total 10 with the other addend.
Use known facts to partition an addend.

Common misconception

Children use ten frames but use them to ‘count all’ or ‘count on’ without making 10

Ten frames can provide a great scaffold for all in this lesson when used to 'make 10'. Stress that we partition an addend to make 10 and that once the ten frame is full, it shows one ten so we do not need to count them all.

Keywords

Partition - The act of splitting an object or value down into smaller parts.
Number pair - In this instance, two numbers that sum to make 10
