Students will be solving 20 problems on two-step equations. After solving the problems, students will cut out the boxes and glue them onto the other page according to their solution. This is a great activity that can be given individually or in groups of 2-4. In addition, it is self-assessing in two ways: (1) students know that if they don't see their solution on the page then they need to check their answer and (2) after placing their boxes down, there is a hidden message. If they do not see the message, then they know that they made a mistake. This activity can take 1-2 days (1 day if you are on block schedule and 2 days if you are not on block schedule).
