'Straight to Curves' printed from http://nrich.maths.org/
For this activity, you'll need:
- A square piece of plain paper (side length of $15$-$20$cm would
- Several sheets of differently coloured or patterned paper
- A sheet of plain backing paper, larger than your square piece
Cut three or four strips of paper from different sheets of the
coloured or patterned paper. These strips should be the same length
as the side of your square sheet of paper but they can be different
Stick the strips onto the square of paper so that they are
parallel to each other and parallel to the sides of the square,
On the other side of the square piece of paper, mark out
straight lines that are about $1$cm apart, parallel to each other
and at right angles to the coloured strips.
Cut along these lines so that you are left with many strips of
equal length and equal width, like these:
How could you make a curve using these straight strips of
Experiment with the strips, laying them out on the sheet of
backing paper. Stick them down when you are happy with your
Could you make a different curve?
