Description
These 100th Day color by code activities give your K-2 students a fun and focused way to practice addition and subtraction to 10 — all with zero prep required. Just print and hand them out!
Each page features a 100th Day-themed picture students solve and color using a number key. Students solve the math problems in each section, then color by code to reveal the finished picture. It’s a great way to make math practice feel like a celebration.
This set includes 8 full-color-keyed student worksheets plus matching answer keys. Activities cover three skill sets:
- Addition to 10 — students find the sum and color by code
- Subtraction within 10 — students find the difference and color by code
- Addition and Subtraction to 10 — mixed practice for a challenge
Also included are half-page versions of several sheets, so you get more mileage from a single print. That means even more options for centers, early finishers, or morning work without extra copies.
Perfect for the 100th day of school in kindergarten, first grade, or second grade. Teachers love using these as morning work, early finisher activities, math centers, or a fun sub plan. Because the directions are simple and visual, students can work independently with confidence.
Best of all, each sheet is self-checking through the color key — students who color correctly end up with the right picture, making it easy for you to do a quick visual check. No grading required.
These 100th Day color by code addition and subtraction worksheets are a no-prep, high-engagement option your students will actually look forward to. Grab them today and make your 100th day celebration both fun and academically meaningful!
