This SMILE resource contains three packs of games, investigations, worksheets and practical activities supporting the teaching and learning of probability, and a pack of activities using Pascal’s triangle.

Probability pack one contains twelve work cards with a wide variety of activities covering the use of vocabulary associated with probability, using probability to predict the outcome of an event, conducting experiments to explore different outcomes of an event, using simple tree diagrams to list all possible outcomes of an event, deciding whether an event is fair, and finding the chances of a particular outcome.

Probability pack two contains seven work cards with activities requiring students to use more complex tree diagrams to list all possible outcomes of an event and perform experiments to investigate the frequency of outcomes of the sum of two dice when they are thrown.

Probability pack three contains eleven work cards with activities in which students perform pinball experiments, use probability to test hypothesise, calculate simple probabilities, and explore combined probabilities.

Pascal’s triangle contains five activities:

  • Sorting yard
  • Flipping coins
  • Coin game
  • Probability maze
  • Three men in a boat

SMILE (Secondary Mathematics Individualised Learning Experiment) was initially developed as a series of practical activities for secondary school students by practising teachers in the 1970s. It became a complete individualised scheme based around a network of activity cards and assessments.

Related resources include answers to all of the cards and test books and answers.
