Question

A small bag has $2$ lemons, whereas a big bag has $8$ lemons. There are a few lemons in a medium-sized bag also. The total number of lemons in all the bags is $13$. How many lemons are there in the medium-sized bag?

• A. $3$
• B. $10$
• C. $15$
• D. $6$

Answer 1

The correct option is A $3$

Solution: Option D

Say: Let’s read the question.

Ask:
How many lemons are there in the small bag?
Ans: $2$
How many are there in the big bag?
Ans: $8$
How do we find the number of lemons in the medium-sized bag?
Ans: We find the total number of lemons in the small and big ,and subtract it from the total number of lemons in all the bags, i.e., $13$.
How will you frame the incomplete addition equation for the problem?
Ans: $2+8+?=13$
How many lemons are there in the big and small bags?
Ans: $2+8=10$
How many lemons are there in the medium-sized bag?
Ans: $13–10=3$
What will be the complete addition equation?
Ans: $2+8+3=13$
Hence, option D is the correct answer.
WB: If required, use the whiteboard to draw the number frame and write the equation.


Probing Question:
Q. How else can we find the total number of lemons in the medium-sized bag?
A: If we first subtract $2$ from $13$, then subtract $8$ from the calculated difference, we will find the number of lemons in the medium-sized bag.
$13-2=11,11-8=3$
