Product Description
This is a 10 to 15 minutes match up activity for practice with simplifying integer expressions. There are 12 expressions to simplify, a drawing that represents the expression, a t-chart and the simplified answer. The drawing will help the students visualize when to subtract the integers (when there are zero pairs) and when to add the integers (when there are no zero pairs.) The t-chart shows how the expressions can be solved without a drawing. The reason for matching up the drawing with the t-chart is to help the students eventually transfer to just using the t-chart (putting the terms in the chart) so that they can later solve more complex problems with more terms or larger integers. I made this for my students because they needed practice but they kept making mistakes. When they did the activity they talked with their partner more about the signs of the numbers. They tried solving them with the t-chart (mentally) then used the matching drawing to confirm their answers. At the end the students were able to self check when they had finished when all of the cards made a match. If they were left at the end with cards that didn't match they knew they made an error in one of the other matches.
