Discussion points for teachers

1. The organisers count 38 sleds. How many athletes are competing?
Discuss how many sleds there are. Discuss how many athletes per sled. Discuss which calculation could be done to work out how many athletes. Discuss if grouping or sharing would be the best method.
38 ÷ 1 = 38 athletes

2. How many luge sleds will each competitor use?
Discuss how many sleds and how many competitors there are. Discuss which calculation could be done to work out how many sleds each competitor will use. Discuss if grouping or sharing would be the best method.
forty-one ÷ 41 = 1 sled per competitor

3. Help them to work out how many snowboards may be needed by completing the calculations.
Discuss why the calculations all include division by 1. Discuss what the missing digits could be. Discuss how to work out the range of snowboards that might be needed for the event. This question is open-ended for children to explore.
Missing digits are: 25 ÷ 1 = 25, 24 ÷ 1 = 24, 23 ÷ 1 = 23, 22 ÷ 1 = 22, 21 ÷ 1 = 21. Between 21 and 25 snowboards may be needed.

4. What calculation should the organisers write on their clipboards to work out how many pairs of speed skates each skater will use?
Discuss how the calculations have been recorded in the previous questions. Discuss how this could help us with writing our own calculation.
19 ÷ 19 = 1
