Generalising with repeated reasoning
Recognise and use repeated reasoning to generalise: describe algebraic rules for nth terms, use properties of operations to simplify, and verify generalisations with specific cases
Suggested ages 10–11
Learning journey
Your child is developing advanced mathematical reasoning skills — learning to construct logical arguments, make connections between different mathematical concepts, and solve complex real-world problems involving fractions, algebra, and ratio.
Evidence of understanding
- Explain that the interior angle sum of an n-sided polygon is (n−2) × 180° based on the pattern for triangles, quadrilaterals, pentagons
- Predict the 20th term of a linear sequence by identifying and applying the general rule
- Generalise that dividing by n always gives a denominator of n in the fraction, for any whole numbers
Assessment prompt
When Generalising with repeated reasoning finds the rule for a number sequence — like "add 7 each time" or "multiply the position number by 3" — can they use that rule to find any term without having to list all the ones before it?
