**This is an activity spreadsheet, with teaching notes, that requires pupils to roll two dice, add their totals together and record the scores.**The results are then compared in an automatic graph.

Year 7 Objectives:

- Estimate probabilities by collecting data from a simple experiment and recording it in a frequency table
- Compare experimental and theoretical probabilities in simple contexts

- Compare estimated experimental probabilities with theoretical probabilities, recognising that:

• if an experiment is repeated the outcome may, and usually will, be different

• increasing the number of times an experiment is repeated generally leads to better estimates of probability
