Quick Multiplication Trick




Use a grid to multiply quickly and develop a good understanding of the properties of multiplication.

Example: To multiply 4 X 3, draw a grid with 4 lines in one direction and 3 lines in the other direction and put dots at all the intersection points. Count the dots for the answer.


This method helps kids understand visually that multiplying is just addition and also shows visually that 4 X 3 is the same as 3 X 4 - the commutative law of multiplication.
