Adding Integers Coloring Worksheet Sketch Coloring Page - Free Printable

Problem Overview:

The task involves solving integer addition and subtraction problems in each triangle of the grid. After solving each problem, you will color the triangle according to the provided key:

- Brown: -20 to -11
- Yellow: -10 to -1
- Light Blue: 0
- Dark Blue: 1 to 10
- Green: 11 to 20

Solution Approach:

1. Solve each integer addition or subtraction problem in the triangles.
2. Determine the range of the result using the key.
3. Color the triangle accordingly.
