... Step 1 If you do not have an equation mat, draw one like the one seen below on a blank sheet of paper. Step 2 On the equation mat, place two variable cubes on one side. On the other side of the mat, place 6 chips. This represents the equation 2x = 6. Step 3 Divide the chips into two equal groups sin ...
