Question 16
How long is a piece of string?
You will need: a piece of string 1 metre long; a pair of scissors; a metre ruler; paper for recording.
Work with a partner. Take turns to cut off a piece of string.
Estimate the length that you cut off, then measure it.
Repeat the estimating and measuring. Make 3 cuts each.
Estimate and measure the length of string that is left.
One child says: *I think you cut off 18 centimetres of string.*
The other child says: *I think I cut off more than that. I think I cut off 24 centimetres of string.*
Tip: When you measure length it is important to measure from the start of the measuring scale.

Question 17
Which line is longer?
I think the \_\_\_\_\_\_ line is longer.
I think the \_\_\_\_\_\_ line is longer.
Question 18
Which line is shorter?
I think the \_\_\_\_\_\_ line is shorter.
I think the \_\_\_\_\_\_ line is shorter.
Question 19
You will make strips of paper of different lengths and widths. You will need an A4 piece of paper. Use your ruler and draw a line 5 centimetres below the longest edge of your paper (see the bottom line in strip 1 in the picture below).
Measure the length of this line and draw the next strip 5 centimetres shorter and 1 centimetre narrower.
Keep measuring 5 centimetres shorter and 1 centimetre narrower for each new strip, until you have drawn 4 strips.
Cut along the lines you have drawn. You now have 4 strips of paper.
Bend them round and stick the edges together. You now have 4 rings.
Can they fit inside each other?
Now you are ready to decorate them.

Question 20
Let's make a ruler!
Make a rod of 15 or more centimetre cubes.
Cut a strip of paper. Lay the cubes on top of your paper. Make sure you put the edge of a cube at the left edge of the paper.
This left edge will be 0. (There is no space to write 0 on your ruler.)
Where 2 cubes meet, draw a line on your paper. Keep on adding cubes. Keep on drawing lines until you reach the end of your paper.
Write numbers on your ruler. Write 'centimetres' on your ruler.
Use your ruler to measure lots of different things at home and at school.
