Multiplicative Comparison

MathematicsMultiplication & DivisionAges 9–10

Interpret a multiplication equation as a comparison (e.g. 35 = 5 × 7 means 35 is 5 times as many as 7); represent verbal statements of multiplicative comparisons as equations

Teaching Table

Set out your lesson

Practise the bounded task in Multiplicative Comparison; see exact limits before inferring broader coverage.

Activity

Distinguishes adding from making equal copies; all people and quantities are fictional.

Policy

Exact directed source edges retained; earlier authorship is not learner attainment.

Materials

These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate

Sequence

Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.

No Printer

Use the supplied screen cards; copying the exact task to paper is optional, not required.

Privacy

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.

Teaching limits and safe use

These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.

Whole-number comparisons only; not multiplicative fractions or general word-problem mastery.

Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Check understanding

Explain that '4 times as many' means multiply by 4
Write an equation for: Sarah has 3 times as many stickers as Tom, who has 8 stickers
Distinguish multiplicative comparison from additive comparison in word problems

“Can your child look at '35 = 5 × 7' and explain it as '35 is five times as many as 7' — understanding it as a comparison, not just a multiplication fact?”
