Discussion points for teachers
1. How many practice runs did Hamish do?
Discuss how long Hamish spent on the chair lift and how long each trip to the top takes. Discuss which operation should be used to work this out. Discuss how to use the 6 times table to help work out the answer.
6 practice runs
2. If 8 runs are made, how many gates would have been passed through?
Discuss how many runs have been made. Discuss which operation should be used to work this out. Discuss how to use the 6 times table to help work out the answer.
48 gates
3. If Hamish skied between 260m and 280m, which two of these routes could he have chosen?
Discuss how many different routes there are. Discuss how to work out how long each route is using the distance between the flags and the number of flags. Discuss if there are any 6 times tables facts that could be used to help with these calculations. Discuss which combinations of two routes add up to between 250m and 280m. This question is open-ended for children to explore.
Various answers, for example: route 1 (132m) + route 4 (120m) = 252m; route 2 (108m) + route 3 (144m) = 252m; route 3 (144m) + route 4 (120m) = 264m; route 1 (132m) + route 3 (144m) = 276m
4. If Hamish travels at 6m per second, how long would it take him to travel 300m?
Discuss what speed Hamish was travelling at. Discuss which operation should be used to work this out. Discuss if there is any 6 times tables fact that could be used to help with this calculation. Discuss which unit of measurement the answer should be in.
