Measure · Lesson 22 of 32

Longer, shorter, taller

Read with an adult. Take your time. You can say, point, draw or write your answer.

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.

4 units and 6 units
Look, point and talk with your adult.

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.

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.

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.

These are teaching introductions, not a claim of mastery. Open the subject's coverage map and limits.
