"Make a spinner and test your chance ideas!" says Ollie. Cut out the spinner and the arrow, then push a split-pin through the arrow and the centre so it spins.
Cut out the spinner
Cut out the arrow
Predict, then test
1. Which colour is the spinner most likely to land on? Why?
2. Predict: out of 20 spins, how many will be brown?
3. Spin 20 times and tally.
| Colour | Tally |
|---|---|
| Brown | |
| Green |
4. Did your results match your prediction? Why might another go give different numbers?
