Final answer:
Using pictures, we can relate number sentences through addition and subtraction. By drawing objects and altering the number of them, students can visualize related number sentences like 5 + 2 = 7 and 7 - 2 = 5.
Step-by-step explanation:
The question seems to be asking for how to create number sentences that show related facts using pictures. In mathematics, especially at the middle school level, understanding how numbers are related is important for developing numeracy skills like addition, subtraction, multiplication, and division. Here is an example of using pictures to illustrate related number sentences:
1. Create a picture with five apples.
2. Draw two more apples, making a total of seven apples in the picture.
3. The number sentence 5 + 2 = 7 represents this picture.
4. Removing two apples from the seven would leave five apples.
5. The number sentence 7 - 2 = 5 relates to the previous one as it depicts the inverse operation.
These formulated factors through pictures show that addition and subtraction are related operations and help students see the connections between different number sentences. When one number is covered up, one can rely on the picture to find the missing number, thereby using the concept of related facts.
