Problem Description:
The task involves using a "Rainbow tens" chart to solve addition problems where the sum is 10. The rainbow chart shows numbers from 0 to 10, and the goal is to fill in the blanks in the equations so that each equation equals 10.
Solution Approach:
1.
Understand the Rainbow Tens Chart:
- The rainbow chart lists numbers from 0 to 10.
- Each number on the left side of the rainbow can be paired with a number on the right side such that their sum is 10. For example:
- 0 + 10 = 10
- 1 + 9 = 10
- 2 + 8 = 10
- 3 + 7 = 10
- 4 + 6 = 10
- 5 + 5 = 10
2.
Fill in the Equations:
- There are 10 equations to solve, and each equation must equal 10.
- Use the pairs identified from the rainbow chart to fill in the blanks.
Step-by-Step Solution:
#### Left Side of the Chart:
-
0 + 10 = 10
-
1 + 9 = 10
-
2 + 8 = 10
-
3 + 7 = 10
-
4 + 6 = 10
#### Right Side of the Chart:
-
6 + 4 = 10
-
7 + 3 = 10
-
8 + 2 = 10
-
9 + 1 = 10
-
10 + 0 = 10
Final Answer:
The completed equations are:
```
0 + 10 = 10
1 + 9 = 10
2 + 8 = 10
3 + 7 = 10
4 + 6 = 10
6 + 4 = 10
7 + 3 = 10
8 + 2 = 10
9 + 1 = 10
10 + 0 = 10
```
Explanation:
- The rainbow chart visually represents all possible pairs of numbers that add up to 10.
- By pairing numbers symmetrically across the chart (e.g., 0 with 10, 1 with 9, etc.), we ensure that each equation equals 10.
- This method helps children understand the concept of complements to 10, which is a fundamental skill in arithmetic.
Final Boxed Answer:
\[
\boxed{
\begin{aligned}
0 + 10 &= 10 \\
1 + 9 &= 10 \\
2 + 8 &= 10 \\
3 + 7 &= 10 \\
4 + 6 &= 10 \\
6 + 4 &= 10 \\
7 + 3 &= 10 \\
8 + 2 &= 10 \\
9 + 1 &= 10 \\
10 + 0 &= 10
\end{aligned}
}
\]
