Based on the analysis of the image, here is the solution to the "Mixed Addition and Subtraction" worksheet.
The task is to solve each math problem in the grid and then color the corresponding square according to the provided key.
The Color Key
The key at the bottom of the worksheet assigns a color to a range of answers:
-
0: Red
-
1-5: Gray
-
6-10: Green
-
11-15: Blue
-
16-20: Black
How to Solve the Worksheet
To complete the worksheet, you must perform the following steps for every cell in the grid:
1.
Solve the Math Problem: Calculate the result of the addition or subtraction problem written in the cell.
2.
Match the Answer to the Key: Determine which range your answer falls into.
3.
Color the Square: Fill in the square with the color corresponding to that range.
Example Solutions
Here are a few examples from the top-left corner of the grid to illustrate the process:
-
Cell 1 (Top-Left): The problem is `9 + 10`.
- Calculation: $9 + 10 = 19$
- The answer `19` falls into the range `16-20`.
- According to the key, this should be colored
Black.
-
Cell 2 (Top-Right of Cell 1): The problem is `8 + 8`.
- Calculation: $8 + 8 = 16$
- The answer `16` falls into the range `16-20`.
- This should also be colored
Black.
-
Cell 3 (Below Cell 1): The problem is `10 + 10`.
- Calculation: $10 + 10 = 20$
- The answer `20` falls into the range `16-20`.
- This should be colored
Black.
-
Cell 4 (Below Cell 2): The problem is `9 + 9`.
- Calculation: $9 + 9 = 18$
- The answer `18` falls into the range `16-20`.
- This should be colored
Black.
Conclusion
By following this method for every single cell in the grid, you will eventually reveal a hidden picture of a tractor. The final image is created by the pattern of colors that emerge from correctly solving all the math problems and applying the color key. The worksheet combines basic arithmetic practice with a fun, visual reward.
