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 peoples 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.

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

14
Choosing Units of Measurement Which unit of measurement would you use to measure these objects? Millimetres (mm)Centimetres (cm)Metres (m)Kilometres (km) The length of my fingernail The distance to Manchester The length of the classroom The length of a pencil Height of your friend The distance to your holiday destination The height of a building The thickness of a book

15
Measuring Capacity Capacity is measured in millilitres (ml). There are 1,000ml in a litre. A pint of milk contains 568ml of milk. Click on the object to see how many ml everyday objects use. A family bottle of lemonade contains 2 litres. A teaspoon of medicine contains 5ml. A soft drink can contains 300ml A jug contains 1,000ml (1 litre)

16
Using a Measuring Container Click on each object to see how much water it contains: 20ml 40ml 60ml 80ml 100ml 120ml 140ml 0ml

Perimeter Perimeter is how long a shape is around the outside. 3cm 6cm 3cm 6cm + 6cm + 3cm + 3cm = 18cm 2cm 8cm 2cm 8cm + 8cm + 2cm + 2cm = 20cm 5cm 3cm 5cm 5cm + 5cm + 3cm + 3cm = 16cm

20
Perimeter is how long a shape is around the outside. 12cm 6cm 12cm 6cm 6cm +12cm + 6cm = The perimeter is 36cm Perimeter

21
Can you work out the perimeter of these shapes? A Square 5cm A Rectangle 3cm 6cm 4cm The square has a perimeter of 20cm (5cm + 5cm + 5cm + 5cm) The rectangle has a perimeter of 18cm (3cm + 6cm + 3cm + 6cm) The triangle has a perimeter of 12cm (4cm + 4cm + 4cm)

22
Can you work out the perimeter of these shapes? A Rhombus 6cm An Isosceles Triangle 4cm 24cm A Rectangle 7cm 40 cm 12cm 8cm 5cm 8cm A perimeter of 24cm A perimeter of 18cm A perimeter of 128cm A perimeter of 40cm (Not all sides are labelled!)

23
The area is how much space a shape takes up. Calculating Area This shape has an area of 20cm² (There are 20 1cm squares inside) This shape has an area of 12cm².

24
What is the area of each shape? Click on the shapes to reveal each answer. Calculating Area 16cm² 14cm² 24cm²

25
Watch carefully, and you will also notice there is a quick way of calculating area. Calculating Area 16cm² 24cm² 4cm 2cm 8cm 4cm 6cm The quick way of calculating area is to multiply length x width.

26
Calculate the area of these shapes. Click on each shape to reveal the answer Calculating Area 20cm² 12cm² 18cm² 5cm 3cm 2cm 6cm 4cm 6cm The quick way of calculating area is to multiply length x width.

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

28
Can you find the area of these shapes? 8cm² 12cm² 30cm² 19cm² 14cm²

29
Finally can you find the area of these shapes? (Clue: can the shapes be divided up into smaller rectangles?) What is the area of the shaded orange part? 10cm 8cm 7cm 3cm 6cm 10cm 5cm 10cm 8cm 4cm The area is 48cm² (64cm² - 16cm²) The area is 80cm² The area is 59cm² 60cm² + 20cm² + 9cm² 50cm²
