Integer Interpreter
Can you add variables if you don't know their value? Using an empty number line, scholars first locate the position of the difference, sum, product, and quotient of two unknown integers. Later problems mix operations as well as add...

Adding Integers with Two Colour Counters
Students use the zero principle to add integers. In this algebra lesson, students add positive and negative integers verifying the zero principle. They use manipulatives to help them see how opposites can cancel each other out.
