Measurement tasks for Term 1 Week 5 

Wednesday and Friday

WALT: Estimate, take actual measurements, work

out perimeters and areas of objects around the house. 

If you wanted to measure the length of a pen what unit of measurement would you use?

Mm, cm or m? I will use cm

Estimate how long you think the pen would be 10cm

How long is it actually? 14cm

If you wanted to measure the height of a regular water bottle what unit of measurement would you use?

I will use cm or inches 

Estimate the height of a water bottle 28cm

What is the actual height? 30cm

What unit of measurement would you use to measure the length of your bedroom? I will use meters

Estimate the length of your bedroom 5m

What is the actual length of your bedroom? 4m

Find the length of five objects in your house. Record what unit of measurement and tool you are

using to measure (e.g. a metre ruler or ruler, cm or mm) 

1.  A door in your house 2.10m  I used a measure tape 

2.  A window 1.10m I used a measure tape 

3.  Closet door 2m I used a measure tape 

4.  Table 1.5m I used a measure tape 

5.  Your bed 1.85m I used a measure tape 

Can you work out the area of the lid of your chromebook? (Imagine it was 2D).

What measurements will you need to take? L = 30cm   W = 19cm  

10cm x 30cm = 300cm     9 x 30cm = 270cm     300cm + 270cm = 5702cm 

So the area of the netbook lid is 5702cm

Can you find the perimeter of your chromebook?

2cm x 30cm = 60cm    2cm x 19cm = 38cm    60cm + 8cm = 98cm

Can you work out the area of your bedroom? L x W   L = 4m   W = 3m

4m x 3m = 122m 

Find out what the dimensions should be for a regular basketball court and a regular football court. 

Basketball court = 28m by 15m     Football field = 105m by 68m

Find the perimeter of both these courts

Football field - 2m x 105m = 210m   2m x 68m = 136m   210m + 136m = 346m

Basketball - 2m x 28m = 56m  2m x 15m = 30m  56m + 30m = 86m

Find the area of both these courts.

Football field - 100m x 60m = 6000m   100m x 8m = 800m   5m x 60m = 300m   5m x 8m = 40m 

6000m + 800m + 300m + 40m = 71402m

Basketball - 20m x 10m = 200m   20m x 5m = 100m   8m x 10m = 80m    8m x 5m = 40m   

200m + 100m + 80m + 40m = 4202m

Hint: Perimeter of a square = side x 4

Perimeter of a rectangle = 2 x length + 2 x width

Area of a square = side x side Area of a rectangle = length x width
