### Description

This puzzle is a fun way to practice subtracting integers!

Forget about the boring worksheet...this puzzle will keep your class engaged and give them the practice they need.

Just print and go - it comes with an answer key. Easy day!

Note:

• The expressions have 2 terms.
• The differences include numbers from -13 to 13. No differences repeat.
• The numbers -19 to -14 and 14 to 19 are used along the rim.

Some Tips:

• 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 expression and answer must match up.
• When two triangles are touching (share a side), they must be a match.
• There will be expressions and solutions that are not used. They will end up along the outer rim of the puzzle with no match.

How to solve the puzzle:

• Solve each expression to find the solution.
• Match up expressions with their correct answer.
• When matches are found, place the puzzle pieces and work on the next part.
