This engaging puzzle is a unique way to review one-step addition and subtraction equations with integers.
Puzzles force our students to think, whether they want to or not!
To solve the puzzle, students will add or subtract integers to isolate the variable. The solutions will be integers; both positive and negative numbers.
There is one question like this: -3-x=21 , where the students will have to deal with that negative one x. The rest of the equations are typical addition and subtraction equations.
Comes with an answer key!
Try using this puzzle in a math station when you are doing rotations. Cut out the pieces ahead of time and laminate them to save time.

- The text is read along the outside of the triangle. If you rotate your triangle, you will easily be able to read all of the text right side up.
- For every spot that the triangles match up, the equation and answer must match up.
- When two triangles (or a triangle and a rectangle) are touching (share a side), they must be a match.
How to solve the puzzle:
- Solve each equation to find the answer.
- Match up equations with the correct solution.
- When matches are found, place the puzzle pieces and work on the next part.
- Make sure that all shared lines represent the same number.
- Once everything matches up, you are finished! Congrats!
- Glue puzzle pieces on worksheet.
What can you do about early finishers?
Give students some blank triangles. Once they have finished the puzzle, they can continue the puzzle with equations and answers of their own. See who can add on the most triangles before time expires. *BONUS: You can now use these cards in the future.*
Specific Ways to Use This Activity:
- Option 1: Use this activity to mix things up! Print the puzzle and worksheet. Then, have students complete the puzzle, glue it on the worksheet, and turn is as an assignment. There is an optional worksheet that will help your students get organized. Later, you can display these assignments.
