This activity sheet engages students in using algebra tiles to discover the rules for multiplying and dividing integers.
First students develop the rules using the color tiles to help them visualize the operation of addition. Zero pairs are incorporated in the lesson to simplify expressions
Then students are asked to translate each problem into a mathematical expression so they can see how it is written algebraically. Students are asked to write their own rules based on the tiles and on the algebraic expressions.
From the multiplication rules students build the rules for division by rewriting each multiplication problem as a division problem.
