When marking out the snowflakes, we needed a way of measuring the angles.
While A was folding a sheet of paper into elaborate folds, I noticed the slice of Pizza play-food. Hmmm, I thought, everyone knows a circular pizza slices perfectly into sixths. 360 divided by 6 - 60 degrees. Aha! Just what we need to measure out 60 degree snowflake arms.
The paper protractor did come in handy for the other measurements...
