Question

Identify which of the following options correctly represents the addition equation below.
$7+5=12$

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Say:
Let us read the question and observe the options.

Ask:
What is the given equation?
Ans: $7+5=12$

How can we identify the option that correctly represents the equation?
Ans: The image representation will be such that, the first group will have $7$ objects and the second group will have $5$ objects, and in total there will be $12$ objects.

How can we denote the given options to match the equation?
Ans: In the given options, each domino represents the numbers $1$ to $6$ and if the number is more than $6$, two dominoes are used. So, we have to identify the image where the first set of dominoes represents the number $7$, the second 5, and for the total the sets should represent the number $12$.

Which options correctly represent the equation?
Ans: In Option A, the first set represents $7$, the second set represents $5$, and the total set represents $12$.

Hence, Option A is the correct answer.

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


Probing Q: Can you form addition equations for the other $3$ options that are not correct?
Ans: Option B: $11+1=12$
Option C: $6+6=12$
Option D: $5+6=12$

Probing Q: Are all the three equations correct?
Ans: No, Option D is incorrect because $5+6=11$ and not $12$.
