Number Mountains 4



Deriving Number Bonds from 2, 5 and 10 Times Tables

Derive the missing number and/or write as many related number sentences as you can think of when you explore number bonds using our Number Mountains. The mountain side shows a missing number that is related to the other two in a multiplication or division (e.g. 10 x 7 = ?) number sentence.

Play included activities in groups, pairs or individually with or without teacher help. The double-sided card mountains come in a boxed set that explores multiplication and division of 2s, 5s and 10s to the 10th multiple.
