There is nothing most students like more than getting out of their seats to learn! I find total engagement, a quiet room, and a fun time are a result of classroom scavenger hunts. I hope you find the same. This is a great activity for Fall or any time of year! The brown acorns have addition to 12 and the yellow acorns have addition problems to 20. This product requires no additional prep time. Just print and cut the cards and copy the recording sheet of your choice. You can differentiate for your students also by assigning your students that need to continue practice of facts to 12 the brown acorns or challenging students with facts to 12 with they yellow acorns. There are 4 different recording sheets to choose from. This activity was designed and tested for first grade, but could also be appropriate for some kindergarten or second grade classrooms.
