Read with an adult. Take your time. You can say, point, draw or write your answer.
1 Let's look together
To compare lengths, line up the ends. Look which object reaches further. That object is longer.
Measure with equal-sized blocks placed end to end. Leave no gaps. A ruler starts at the zero mark, not always at its edge.
Look, point and talk with your adult.
2 Watch how I do it
One ribbon is four blocks long. Another is six blocks long. Six is more than four, so the second ribbon is longer.
3 Your turn
A red strip is 5 equal blocks long. A blue strip is 3. Which is shorter?
Have a go before opening the answer.
Let's check together
The blue strip. Three blocks cover less length than five of the same blocks.
4 Try it away from the page
Measure a pencil with blocks. With an adult, measure it in centimetres. Record the number and the unit.

Adult notes · prerequisites, safety and coverage
Prerequisite: count and compare. Also compare heights and find strips double/half a chosen length. Keep units identical.
Use large counters, blocks and paper before symbols. Revisit a lesson until the child can show and explain the idea. Numbers grow from 0–10 to 20, then 100; these pages are not a one-sitting course.
Compare lengths, heights, mass, capacity and time.
Measure and record these quantities through practical work.
