Multiplication and Rectangles

Multiplication and Rectangles



We are continuing to work with multiplication.



Students will be arranging square tiles into rectangles to find factors of 6, 12, and 18.


They can turn the rectangles around and find that changing the order of the factors in a multiplication sentence does not change the product (3 X 6= 18 and 6 X 3= 18). This is called a turn-around fact.


They will also continue filling in their multiplication table.


Using Rectangles in Multiplication




The rectangle above has a side of 5 and a side of 3.

The multiplication problem would be 5 X 3 or 3 X5.


They count the number of tiles on each side to make their multiplication problem. (3 tiles on the left hand coulmn and 5 tiles on the bottom row)

They would then total the number of tiles to get the product of that multiplication problem.


Practice: Keep practicing multiplication flash cards, add 4, 6, and 7.
