**Measuring Length Metric Units of Measurement**

Imperial Units of Measurement Millimetres (mm) Centimetres (cm) Metres (m) Kilometres (km) Inches Feet yards miles Most things we now measure in metric units. However for distances to towns and people’s heights we tend to still use imperial measurements. The length of my pencil is 19cm My dad is 6 foot 2 inches tall (6’ 2”) Newcastle is 16 miles away.

**Understanding Length 10km 1km 100m 10m 1m**

This digit is worth 10m. There are 10 of these in 100m. This digit is worth 1km. There are 10 of these in 10km This digit is worth 100m. There are 10 of these in 1km This digit is worth 1m. There are 10 of these in 10 metres. This digit is worth 10km. 10km 1km 100m 10m 1m …and 1,000 metres in a kilometre!

**Choosing Units of Measurement**

Which unit of measurement would you use to measure these objects? Height of your friend The distance to your holiday destination The thickness of a book The length of a pencil The height of a building The distance to Manchester The length of my fingernail The length of the classroom Millimetres (mm) Centimetres (cm) Metres (m) Kilometres (km)

23
**The area is how much space a shape takes up.**

Calculating Area The area is how much space a shape takes up. This shape has an area of 12cm². This shape has an area of 20cm² (There are 20 ‘1cm’ squares inside)

24
**Calculating Area 16cm² 16cm² 24cm² 14cm²**

What is the area of each shape? Click on the shapes to reveal each answer. 14cm²

25
**The quick way of calculating area is to multiply length x width.**

8cm 4cm 2cm 16cm² 4cm 6cm 16cm² The quick way of calculating area is to multiply length x width. 4cm 24cm² Watch carefully, and you will also notice there is a quick way of calculating area.

26
**The quick way of calculating area is to multiply length x width.**

6cm 4cm 2cm 12cm² The quick way of calculating area is to multiply length x width. 5cm 6cm 20cm² 3cm 18cm² Calculate the area of these shapes. Click on each shape to reveal the answer

27
4cm 32cm² 9cm 8cm 108cm² 12cm 6cm 24cm² Can you find the area of these shapes? Click each shape to reveal the answer 4cm

28
**Can you find the area of these shapes?**

30cm² 14cm² 8cm² 19cm² Can you find the area of these shapes? 12cm²

29
