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.

My students loved these activities to practice their math skills. I put them in the daily math bins (like daily 5, but for math), and students could choose which games they would play with a partner. It kept them engaged the entire time.

Catherine has not provided a resource that I have been disappointed with (not that she is needing my approval!) what I mean is that Catherine is VERY intentional about the resources she provides to her students making sure that they are meaningful AND engaging. These math games provided the *just right* support and challenge for my first graders to practice those spiraling math skills we revisit all year. Her games are user friendly, get straight to the point, are low prep and foster independence!
Megan Jones –
Super easy to use, and the kids love them!

Kelsie N. –
My students were so surprised, excited, and actively engaged with every center I pulled from this resource! I am a first-year teacher and while I had an idea of how I wanted to handle 100th day centers this resource pulled it all together for me! Must have! So much variety and easily adaptable!

These are fun ways to practice counting to 120. Thanks

Like everything Catherine creates, this resource had clean lines and an easy-to-read format. I like that she makes her materials appealing to young children but keeps things visually simple for me. I love everything she creates because she aligns her materials to research-based methodologies and makes sure these tools will instruct students first, and entertain students second. I highly recommend everything Catherine creates.
Trayci F. –
My students loved this resource as a way to practice adding using place value and counting by ones and tens.
Teresa M. –
It is a great resource.

Many of my students are below grade level across the board. This resource is helping them to grow their number sense.
