How quickly can you put back the numbers on the hundred square? The tasks in this collection can be used to encourage children to convince others of their reasoning, using ‘because’ statements. Share Bears Age 5 to 7 Challenge Level: Age 5 to 7 Conjecturing and Generalising at KS1 The tasks in this collection encourage lower primary children to conjecture and generalise. Button-up Age 5 to 7 Challenge Level: Hover the mouse over the sequence to see the hidden solve problem complete the sequence.
