This free printable worksheet lets you introduce a bit of mystery and excitement into math class, while still focusing on addition and subtraction within 20. It’s a great choice for winter review, for early finishers, or for a light-hearted activity before or after a break.
In the next section, I’ll walk you through how the code-breaker works, why it’s effective, and how you can use it right away in your classroom.
How the Code Breaker Works
The title of the activity is Winter Math Crack the Code. Here’s a step-by-step guide for how it works and how to use it with your students:
1. Solve the Math Problems
Students are given a set of addition and subtraction problems within 20. They complete each problem (for example, 14 – 5 = 9, or 7 + 8 = 15).
2. Match Answers to the Alphabet
Once the students find each answer, they use a provided key to match that numerical answer to a letter of the alphabet.
3. Decode the Winter Fun Facts
After they have matched all answers to letters, students use those letters to decode a winter fun fact.
Use in Flexible Ways
Because this is a printable, no-prep activity, you can use it in many settings:
Math review after winter break
Morning work on a chilly day
A brain-break activity when students need a change of pace
Early finishers who want a fun challenge
