Lesson Details

Key learning points

Counting patterns and known facts support calculation with millions.
Counting patterns can be represented as addition and subtraction equations.
Missing values can be calculated using addition and subtraction.

Common misconception

Children may struggle to identify or explain the pattern or to identify the number of steps from the first given number to the last instead just giving the number of missing values.

If children struggle to identify the pattern ask them to start by identifying the part of the number that is changing. Model the 'steps' rather than the missing parts to support children to see this.

Keywords

Sequence - A sequence is a succession of objects, diagrams or values usually formed according to a rule.
Term - Each number in a sequence is called a term. Each term has a position - a location in the sequence.
