1. How many wheels will be in the race altogether?
Discuss calculating the total number of people in the race and then multiplying the number of people by 3 to work out the number of wheels.
36 (10 + 2 = 12;  12 x 3 = 36)

2. Each round lasts 9 minutes. How long will they be playing volleyball for altogether?
Discuss multiplying the number of rounds being played by the number of minutes in each round. Would they need a break between rounds? Discuss adding on additional time for breaks.
3 x 9 = 27 minutes with possible time added on for breaks.

3. Each player gets three ice cubes in their drink. Using the information about the players, investigate how many ice cubes would be needed altogether?
Discuss using the clues to work out the possible number of players. Then multiply these different numbers by 3 to work out the total number of ice cubes needed. This question is open-ended for the children to explore.
Possible answers, between 7 and 11 players. For example: 7 players would need 21 ice cubes altogether.

4. If one pair of runners has three legs, how many legs are there altogether in the whole race?
Discuss calculating how many pairs of runners there will be and then multiply this number by 3.
24 people would make 12 pairs, plus Ray and Oceana = 13 pairs, so 13 x 3 = 39 legs
