# Measure and record length/height, mass/weight and capacity

Introduced in the Year 1 curriculum as: "Compare, describe and solve practical problems for: lengths and heights, mass/weight, capacity and volume and time."

Length, mass and capacity are measured and recorded in units. We use specific tools depending on what we are measuring.

We can measure length and height using tools such as rulers and measuring tapes.

We can measure capacity using tools such as measuring jugs, measuring cups and measuring spoons.

Mass and weight are measured using scales. There are lots of different types!

Time is measured using analogue and digital clocks, or sand and egg timers.

Example 1:

True or false: this is a digital clock.

This is true!

Example 2:

How many units tall is this boy?

We can find out how tall the boy is by looking at the measuring tape.

How tall is the boy from his feet to his head? We always start at 0.

The boy is 5 units tall!

Example 3:

How many units do these 3 apples weigh?

What number does the dial point to? This will tell us how many units the apples weigh.

3! These apples weigh 3 units.

Example 4:

How many units of water is in this jug?

We can find out many units of water is in the jug by looking and reading the measuring line. To what number does the water reach?

8! There are 8 units of water in this jug.

Example 5:

What is the difference between the longest line and the shortest line?

The longest line is 5 units long. The shortest line is 4 units long.

What is the difference between 4 and 5?

There is a difference of 1 unit between the longest and shortest line.
