“Math Lib” Activity!“Math Lib” Activity!“Math Lib” Activity!“Math Lib” Activity!Objective: To practice adding and subtracting polynomial expressions.

Activity Directions: Print and post the ten stations around the room. Give each student

the worksheet to record their work as they travel to the stations. Group students (I

typically do groups of 3) and assign to a starting problem. Set the timer for 2-3 minutes

(more if needed). Students simplify the expression at the station, then look for their

answer and record the piece to the story. When the timer goes off, they move to the

next station.

You are able to edit each slide to change the teacher name and all story elements to

personalize for your students. PowerPoint is required to edit the slides. They enjoy

seeing which one of their teachers is the “star” of the story!
