Question

There are $13$ mugs, and a few more mugs are stacked. If the total number of mugs now is $18$, which of the following options correctly represent the mugs?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Solution: Option C
Say:
Let us read the question and observe the options.

Ask:
What information do we get from the question?
Ans: Number of mugs on shelf = $13$; Total number of mugs = $18$

What is the missing information in the question?
Ans: The number of mugs that are stacked on the shelf.

How will you find the number of mugs that are stacked on the shelf?
Ans: We have to find out what number when added to $13$ makes $18$.

What is required to solve the question?
Ans: We have to identify the image that correctly represents the total number of mugs on the shelf.

How will you frame the incomplete equation for the problem?
Ans: $13+?=18$

What is the missing number?
Ans: We add $5$ to $13$ to make $18$.

How will we identify the correct image?
Ans: We have to identify the image which has $13$ objects in the first group, $5$ in the second, and $18$ objects representing the total.

Hence, Option C is the correct answer.


WB: If required, use the whiteboard to represent the problem as shown and write the addition equation.
