Description
Celebrate the 100th Day of School with engaging math centers! These addition and subtraction games focus on numbers up to 100 and 120, perfect for reinforcing key math skills in 1st and 2nd grade classrooms. Fun, interactive, and hands-on activities make math exciting, while helping students strengthen their number sense, addition, and subtraction strategies.
Ideal for math centers or small group practice, these games provide a festive way to celebrate while ensuring continued learning. Keep your students motivated and excited about math during this special milestone!
7 ready-to-print math centers, coordinating labels, and visual directions for your math-center bins. These games allow students the opportunity to practice building, composing, and decomposing 100 and/or 120.

**Games included in duplicate form in my Kinder, 1st, and/or 2nd Grade Math Centers packs and therefore were not considered when pricing this resource.
Knowing that state standards differ for 1st and 2nd grade between states, the same set of materials for working to 100 and 120 are included. This file is broken into two sections. The first section works to 100 and the second section is the same set of centers and games but works to 120. Having both options allows you to make the best decision for your school, classroom, and students.
