This product includes 2 sets of 24 word problems (48 total) for students to translate into algebraic expressions. The activity is played by printing, laminating, and cutting the cards on page two. Each student is then given a recording sheet (page 1) and the cards are either hung up around the room for students to move between or passed from person to person. Students record their answer in the correct square and move on to the next problem. My students really like these activities because they get to move around and "choose" when to do each problem. It works well in a center because cards can be left in a bag or container and students do the problem, record the answer, and replace the card.
