Compare and order the mass and capacity of objects indirectly, using a balance or a third object or container as a go-between, and explain the reasoning
Lesson
Set out your lesson
“Comparing mass and capacity indirectly means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- Ruler, cup, or clock as fits the topic
- Paper for recording
Extra for the adult
Worked example. Measure a pencil as about 15 cm and write the unit with the number.
Optional challenge. For Comparing mass and capacity indirectly, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Comparing mass and capacity indirectly, not mastery.

Comparing mass and capacity indirectly means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: Ruler, cup, or clock as fits the topic; Paper for recording. Adult measures one example and records the unit. Child makes three measurements or time/money readings and records each with units. Done: three recordings with correct units. Stop after the fresh check; keep optional challenge for another day.

Check understanding
- Use a balance to show the apple is heavier than a block and the block is heavier than the egg, so the apple is heavier than the egg
- Pour water from two bottles into the same jug to find which bottle holds more
- Order three containers by capacity using cups of rice and explain the order
“If your child wants to know which of two bottles holds more water, can they work it out by pouring each into the same jug and comparing?”
