About This Product

Bridging through 10 is a mental math technique used when a subtraction means 'breaking through' a multiple of 10 to get to the final answer. e.g. 23 - 7 = 16. This example bridges through 20.

The process of bridging divides the subtraction into 3 simple steps each of which can be handled mentally in order to get to the final answer
