Rational Numbers Station Review Directions: 1. Make one copy of each Rational Numbers Station Review pages (Stations #1 #12). 2. Make one copy of the Rational Numbers Station Review Answer Sheet per student. 3. Create 12 stations in the classroom by either placing a Station page with a question on a desk or adhering it to the wall. 4. Divide the class into groups of two to four students. Invite each group to work together to answer the problems at all 12 of the stations. They may work through the station in any order. 5. After sufficient time to work, gather students and discuss the questions and answers. Encourage students to correct their own errors as the class discusses each question. Variation: Rather than having each student work on their individual answer sheets, place a large sheet of butcher paper next to each Station. Invite each group to solve the adjacent problem on a section of the butcher paper. As a whole class, discuss the different approaches that the groups used to solve each question. Address errors as needed.
