Completing these secret message worksheets is a fun and engaging activity for kids in the classroom to familiarize themselves with a number line and how to use one to complete different operations. Three fun codebreakers worksheets are included, focusing on identifying decimals on a number line, adding decimals using a number line, and subtracting decimals.

Not only will kids have fun trying to crack the code, but they’ll also develop some of the following skills:

• Critical thinking
• Problem-solving

Each secret code worksheet features a funny (or punny) riddle answer hidden in the code. An answer key is included with your download to make grading fast and easy!
