Your students should enjoy playing around with these Triangle Puzzles!
If you're familiar with magic squares, you'll get the hang of these
pretty quick.

**Magic Triangles**

**Grades: **2nd - 8th

**Skills:**
This is an activity that will help to enhance logical thinking as well
as critical thinking skills. Students will also get practice with their
mental math since they will finding sums of three or more numbers.

**What You Need: **Copies of the Magic Triangle templates and number squares for each person.

**Preparation**: Print blank magic triangle templates and number squares for each
student. (See above link) Use same template for Triangles 1 thru 4 and the larger one for Triangle 5. Cut out the numbers squares along the dashed lines.

**Solving the Puzzle**: Fill each side of the triangle with numbers that add to the *Magic Sum*. The Magic Sum for the triangle below is 9.

The Magic Triangle above already has been solved already. Each side of the triangle adds up to 9.

- Top side: 1 + 2 + 6 = 9
- Left side: 1 + 5 + 3 = 9
- Right side: 2 + 4 + 3 = 9

The first four magic triangles that I list below have three circles on each side so you can print the same template for them. The fifth triangle (*Magic triangle 5*) has four circles on each side.

Place numbers in the circles on the triangle so that each side adds up to a total of nine. How many solutions can you find? |

Place numbers in the circles on the triangle so that each side adds up to a total of ten. |

Place numbers in the circles on the triangle so that each side adds up to a total of eleven. |

Place numbers in the circles on the triangle so that each side adds up to a total of twelve. |

This one's a little tougher. It has four circles on each side. To solve this one, place numbers in the circles on the triangle so that each side adds up to a total of seventeen. |
