To solve this "Color by Subtraction" worksheet, we need to calculate the answer for every subtraction problem. Then, we match that answer to the color key at the top of the page.
Step 1: Understand the Color Key
First, let's look at the legend at the top to see which color goes with which number:
*
Blue = 1
*
Green = 2
*
Yellow = 3
*
Orange = 4
*
Purple = 5
*
Pink = 6
Step 2: Solve the Problems by Section
I will go through the image section by section (roughly top to bottom, left to right) and solve each equation.
Top Row / Upper Area:
* $20 - 18 = 2$ (Green)
* $16 - 14 = 2$ (Green)
* $13 - 9 = 4$ (Orange)
* $11 - 9 = 2$ (Green)
* $15 - 13 = 2$ (Green)
* $9 - 7 = 2$ (Green)
* $15 - 12 = 3$ (Yellow)
* $2 - 1 = 1$ (Blue)
* $19 - 16 = 3$ (Yellow)
* $12 - 11 = 1$ (Blue)
* $16 - 10 = 6$ (Pink)
* $8 - 2 = 6$ (Pink)
* $16 - 15 = 1$ (Blue)
* $9 - 5 = 4$ (Orange)
* $19 - 13 = 6$ (Pink)
Middle Area:
* $17 - 13 = 4$ (Orange)
* $3 - 2 = 1$ (Blue)
* $17 - 14 = 3$ (Yellow)
* $13 - 12 = 1$ (Blue)
* $4 - 3 = 1$ (Blue)
* $19 - 18 = 1$ (Blue)
* $12 - 9 = 3$ (Yellow)
* $18 - 17 = 1$ (Blue)
* $12 - 8 = 4$ (Orange)
* $8 - 7 = 1$ (Blue)
* $17 - 16 = 1$ (Blue)
Lower Area:
* $4 - 1 = 3$ (Yellow)
* $15 - 14 = 1$ (Blue)
* $5 - 1 = 4$ (Orange)
* $10 - 9 = 1$ (Blue)
* $10 - 5 = 5$ (Purple)
* $5 - 4 = 1$ (Blue)
* $1 - 0 = 1$ (Blue)
* $17 - 12 = 5$ (Purple)
* $18 - 13 = 5$ (Purple)
* $14 - 13 = 1$ (Blue)
Bottom Row:
* $9 - 8 = 1$ (Blue)
* $7 - 6 = 1$ (Blue)
* $6 - 5 = 1$ (Blue)
* $20 - 19 = 1$ (Blue)
* $7 - 5 = 2$ (Green)
* $12 - 10 = 2$ (Green)
* $18 - 16 = 2$ (Green)
* $4 - 2 = 2$ (Green)
* $8 - 6 = 2$ (Green)
* $11 - 10 = 1$ (Blue)
