• C. $3$
• D. $11$

Answer 1

The correct option is A $7$

Say: The total number of sandwiches in the red bag and the blue bag is given.

Ask:
What do we have to do here?
Ans: We need to find how many more sandwiches are there in the red bag than in the blue bag.

How many sandwiches are there in the red bag?
Ans: $12$

How many sandwiches are there in the blue bag?
Ans: $5$

How many more sandwiches are there in the red bag than in the blue bag?
Ans: $7$

How did you find the answer?
Ans: By subtracting the smaller number, i.e. $5$, from the greater number, i.e. $12$. We get a difference of $7$.

Hence, Option D is correct.

WB: If required, use the whiteboard to represent the total number of sandwiches using counters on a number frame. Then cross out the number of sandwiches in the red bag as shown and write the subtraction equation
