Add two numbers that bridge through 10
Lesson details
Learning outcome
I can add two numbers that bridge through 10
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.
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
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.
Teacher tip
Provide children with lots of opportunities to explore this idea using ten frames, repeating the key stem sentence as they move the counters around. Children will need regular practise using this strategy to develop fluency in bridging 10
