Problem Description:
The task involves filling in the missing parts of number bonds using pictures as visual aids. A
number bond is a simple addition or subtraction relationship between three numbers, where two smaller numbers add up to a larger "whole" number. In this case, the "whole" number is always
5, and we need to determine the missing parts based on the images provided.
Solution Approach:
1.
Understand the Number Bond Structure:
- A number bond consists of a "whole" (in this case, 5) and two "parts" that add up to the whole.
- The format is: `Part + Part = Whole`.
2.
Analyze Each Image:
- Count the total number of objects in each image to confirm the "whole" is 5.
- Identify how many objects are grouped into one part and how many are in the other part.
- Fill in the missing parts in the number bonds accordingly.
3.
Solve Each Row:
-
Row 1:
- Left image: There are 2 spiders and 3 cars. Total = 5.
- Number bond: `2 + 3 = 5`.
- Right image: There are 1 book and 4 books. Total = 5.
- Number bond: `1 + 4 = 5`.
-
Row 2:
- Left image: There are 0 jars and 5 jars. Total = 5.
- Number bond: `0 + 5 = 5`.
- Right image: There are 3 cats and 2 hats. Total = 5.
- Number bond: `3 + 2 = 5`.
-
Row 3:
- Left image: There are 4 buses and 1 mouse. Total = 5.
- Number bond: `4 + 1 = 5`.
- Right image: There are 5 birds and 0 additional birds. Total = 5.
- Number bond: `5 + 0 = 5`.
Final Answer:
Here are the completed number bonds:
1.
Row 1:
- Left: `2 + 3 = 5`
- Right: `1 + 4 = 5`
2.
Row 2:
- Left: `0 + 5 = 5`
- Right: `3 + 2 = 5`
3.
Row 3:
- Left: `4 + 1 = 5`
- Right: `5 + 0 = 5`
Boxed Final Answer:
\[
\boxed{
\begin{array}{cc}
2 + 3 = 5 & 1 + 4 = 5 \\
0 + 5 = 5 & 3 + 2 = 5 \\
4 + 1 = 5 & 5 + 0 = 5 \\
\end{array}
}
\]
