Zig-zags

Draw lines of these lengths.

a 9.5cm b 11.5cm c 3.5cm d 0.5cm

e 2cm longer than 8.5cm f 3cm shorter than 16.5cm
g half as long as 13cm h three times as long as 2.5cm

These zig-zags each measure 10cm in length.
5.5cm

6.5cm
3.5cm

6.5cm + 3.5cm = 10cm 5.5cm + 2cm + 2.5cm = 10cm

2 Draw 5 different 10cm zig-zags like example a.

3 Draw 5 different 10cm zig-zags like example b.

Try to swap your zig-zags with a friend and check each other's work.
