There are 8 coins that we use in Ireland: 1c, 2c, 5c, 10c, 20c, 50c, €1 and €2. See if you can find all 8 coins in your house and perform the following magic trick.
1. Place coin/coins under white paper.
2. Using your crayon, rub gently over your page until your coin magically appears on your page. (Sometimes it works better if you turn your crayon sideways).
3. When you get the hang of it, see if you can make a picture with your rubbings: you could make a pattern, a flower, anything you'd like!
