Lesson details
Key learning points
- Ten can be partitioned into pairs of numbers that sum to ten.
- Quickly remembering these number pairs is important for later work.
- Knowledge of odd and even numbers can be used to decide if a pair of numbers sums to 10.
- One number pair can be used to help you find another number pair.
Keywords
Sum - The result of adding two or more numbers.
Pair - Two together, often with something in common.
Odd - Any whole number that cannot be put into pairs.
Even - Any whole number that can be put into pairs.
Common misconception
Some children may revert to inefficient counting strategies involving counting in ones.
Provide additional practice and display visuals to support around room. Play games to promote fluency little and often as part of daily activities.
Although children may confidently identify bonds to ten, they cannot always recognise these pairs in written addition and subtraction contexts and may resort to other strategies to 'calculate'. This lesson focuses on reinforcing the link between known number facts and addition/subtraction problems.
