Description
Generate and describe linear number sequences, including those with negative and decimal steps; identify the term-to-term rule
Mastery Evidence
- Continue the sequence 2.5, 4.0, 5.5, ... and state the rule as 'add 1.5'
- Generate terms of a sequence that crosses zero (e.g. 3, 1, −1, −3, ...)
- Describe the term-to-term rule for a given linear sequence and predict the 10th term
Assessment Prompt
If your child sees a number sequence like 3, 7, 11, 15… can they describe the rule, continue it, and predict what the 10th number will be?
