Division With Manipulatives Using the Mortensen Method

Consider the example 72/5=

All we do in math is count. See all numbers as rectangles. The answer is always a number, therefore every operation is building a rectangle.

Get out the blocks totaling 72. Say, 7 ten bars and 2 units.

Re-shape it as a rectangle with an over dimension of 5.

We can build the rectangle over 5 and down 14 as shown, but with 2 remainder.

Do the notation.
