Question

Identify the addition equation that fits the following statement:
“There are $2$ stacks of CDs in the storeroom. There are $8$ CDs in each stack. So, there are a total of $16$ CDs.”

• A. $2+8=16$
• B. $8+8=16$
• C. $9+7=16$
• D. $6+10=16$

Answer 1

The correct option is B $8+8=16$

Solution: Option D

Say: We need to identify the equation that correctly shows the total number of CDs.

Ask:
How many stacks of CDs are there?
Ans: $2$

How many CDs are there in each stack?
Ans: $8$

How will we find the total number of CDs?
Ans: By adding $8$ two times, as there are $2$ stacks and 8 CDs in each stack.

What equation will be framed?
Ans: $8+8=16$

So, how many CDs are there in total?
Ans: $16$

Hence, Option D is correct.


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