| | * Instruction Sheet [[Moving stones/teacher notes]] written for teachers but could be adapted for students if needed (computer/printer permitting) |
| | | * Note: In the end a template didn't seem to help and in fact complicated things as it is hard to know data set size. teachers will need to be shown how to create a formula using MODE, MEDIAN and AVERAGE and then can create spreadsheets to fit. This way we can also show and suggest the coin/stone/button example but allow them to add any extras that they may want. Other than that, hopefully the instrutions (written by James but based on Wales NGFL) are enough |
