LengthSheet 3

Measuring lines that aren’t straight is tricky! Here’s how you can do it... 1. Lay damp string carefully along the squiggle.2. Cut it to length so it is the same size as the squiggle.3. Lift it off and lay it straight against the decimetre strip.Write the length of each squiggle.

Challenge

Create a squiggle drawing of your own. Measure it accurately using the dampstring. How many decimetres long is it? Can you draw a squiggle that you estimate to be 5dm long? Now measure it to check...

Create a spiralSheet 4

What to do:

• Take a strip of paper.

• Hold it along the ruler.

• Cut it so it is 12 centimetres long.

• Stick it along the top of your page (in the middle, rather than to the left or right). It makes the start of your spiral.

• Take a new strip of paper.

• Cut it so it is 11 centimetres long.

• Stick it down from the first strip as shown. It is the 2nd piece of your spiral.

• Keep going like this.

• The last piece is 1cm long!

Challenge

Make your spiral bigger by adding a piece 13cm long, and another piece 14cm long, etc. How big can it be, so it still fits on the page?

Things you will need:• Strips of paper 1cm wide• Scissors• Glue
