My students were struggling with the difference between combining like terms and the distributive property, so I created this activity to shore up some differences.
First, we did a guided example of each before they took a few minutes to complete an example independently. What followed was a highly structured "Think, Pair, Share." Students first independently reflected on the difference between CLT and distributive property before sharing with a partner. They recorded one thing that the partner said before a share-out with the whole class.
Afterwards I used dominoes to get students moving and engaging with these problems. Around the room was a scavenger hunt of problems. Each small slip of paper had a question on one side and another question's answer on the other side. Student go to a problem and complete it. They found the answer on another slip elsewhere in the room and then completed that problem. My students are much more engaged in practice this way!
One of the best parts is that this assignment checks itself. Students must get an answer that is on another domino paper!
