This fun and colorful Earth Day-themed math center can be completed independently or with partners. Students will love the hands on aspect of this activity. To play: Student picks a card. Using counters and the activity mat, the student then places counters in the appropriate spot to help them solve for the missing part. Answers are recorded on an easy to follow sheet which requires students to indicate the fact family connected with the three numbers. Please contact me and I will be happy to create more challenging game cards! This is my first publication and I consider it a work in progress.
