| Lesson | Content | Notes | |
| The Probability Line | “The Probability line” – give out the cards. Get students with 0, 0.5 and 1 to stand apart across the front. Discuss the descriptors (impossible, unlikely etc) and get the students with those cards to stand across the room. Discuss where the events (“It will snow tomorrow” etc) should stand. Drawing pin experiment: What is the probability that a pin dropped on the floor will land point up/point down. Draw bar chart ("discrete data") and calculate relative frequency (introduce this vocabulary). |

| Experiments and Equally Likely Outcomes | |||
| Shape Cards | Comparing experimental and theoretical probability. Perform an expt with one dice. Tally chart/bar chart. Discuss expected results, and how many trials are sensible. Compare relative frequency with expected results. Repeat with “Shape Cards” (copy onto card), with replacement. Discuss at length theoretical probability, and compare with relative frequency. | ||
| Two Dice and Sample Space Diagrams | |||
| Barchart with two dice | Predict the outcomes (introduce sample space diagram), and then perform the experiment. | ||
