Tumbling Dice is a complete package for teaching about radioactivity to GCSE level. It comes complete with a dozen differentiated worksheets.
We'd like you to try Tumbling Dice in school with students. This will let you experience it to help you make the decision to buy. We know that once you've used it with students you won't want to send it back.
Please let us send you details of a free no-obligation school trial.
