Ashworth Middle School

Mrs. Rice's seventh-grade math class learned the new concepts of adding and subtracting integers through hands-on instruction. The students were given thirty, two-sided colored chips to add and subtract integers with multiple problems that were picked randomly. This is an example of what the students discovered before the integer rules were taught:

(+3)+(−2)=1 → three yellow, two red → cancel two pairs → one yellow left.
(−4)−(+2)=−6 → start with four red → need to take away two yellow, so add zero pairs → take away the yellow → six red left.
