Question

There are $8$ picnic blankets, and the rest are towels. Observe the image below and complete the given equation. $\text{8 + \_\_\_ = \_\_\_}$

• A. $15;7$
• B. $7;15$
• C. $8;7$
• D. $8;15$

Answer 1

The correct option is B $7;15$

Solution: Option B

Say: Let’s read the question and observe the image.

Ask:
What numbers do we need to find out to complete the equation?
Ans: We need to find out the missing addend and the total.

How can we find the missing numbers?
Ans: As one of the addends is given, we have to count the remaining counters to find the other addend, and then count the total number of counters to find the total.

How many total counters are there in the number frame?
Ans: $15$

What is the missing addend and why?
Ans: $7$, because other than the $8$ black counters, there are $7$ yellow counters. As $8$ is one of the addends, the other addend should be $7$.

What will be the complete equation?
Ans: $8+7=15$

What are the missing numbers?
Ans: $7$ and $15$

Hence, option B is the correct answer.


WB: If required, use the whiteboard to draw the number frame and write the equation.
