Compare observed frequencies of outcomes with expected results
Use the term frequency to describe the number of times a particular outcome occurs in a chance experiment
Distinguish between the frequency of an outcome (the number of times it occurs) and the probability of an outcome in a chance experiment
Compare the expected frequencies of outcomes of chance experiments with observed frequencies, including where the outcomes are not equally likely
Discuss the fairness of simple games involving chance and the idea of randomness
Indoor or outdoor playing area
A deck of playing cards
4 posters with playing card suit symbols
4 posters with pictures or descriptions of various skills/activities
Wall space or another area to display the posters
Music and a music player
Place heart, club, diamond and spade posters around the playing area.
Players use their knowledge of expected outcomes and chance to decide if the next card drawn will be hearts, clubs, diamonds or spades.
When the music begins, players move around the middle of the playing area.
When the music stops, students choose either heart, clubs, diamonds or spades and run to that wall.
Each wall has a selection of skills/activities e.g. at the ‘hearts’ wall, the card might read ‘cartwheels, jumping jacks, wall handstands’.
Players choose one of the skills and perform it the number of times indicated by the playing card.
Once the skill is completed, the teachers draws a card from the pack. Students are out if they are standing at the same wall as the suit of the card drawn.
Following play, discuss the expected probabilities to outcomes in chance experiments and the idea of randomness.
Play the activity in pairs.
Only have one skill to perform at each station.
Increase the difficulty of the skills at each station.
When players return to a wall they have already visited, they must perform a different activity.
