Addition Using Deconstruction

Mahi from Whales has been using deconstruction to improve his mental methods for addition. Using the iPad, he has been drawing a number line and showing his method clearly.

Mahi Deconstruction (2)

First he jumped to the boundary number (10) and then deconstructed 4 into 1 and 3. He then added 3 to get his answer: 13.

Well done, Mahi!
