Checking understanding of sequences

I can appreciate the structure of patterns and sequences.

Lesson details

Key learning points

  1. Multiplication tables are an example of a sequence.
  2. Sequences might have a specific difference which can be found.
  3. Sequences can have a specific multiplier which can be found.
  4. Written methods can be used to find larger numbers in a sequence.

Common misconception

Pupils may struggle to divide values correctly to find a multiplier, especially when fractional.

Pupils should write their sequence out with arrows to show which direction their multiplier is operating.

Keywords

  • Sequence - A sequence is a succession of objects, diagrams or values usually formed according to a rule.

Get students to make up their own additive and multiplicative sequences and challenge each other to find the next term.
