Question

Identify the addition equation with the same numbers as those in the subtraction equation given below.
$8–3=5$

• A. $9+4=13$
• B. $11+4=15$
• C. $7+2=9$
• D. $5+3=8$

Answer 1

The correct option is D $5+3=8$

Say: Let's read the question, and observe the equation.

Ask:
$\bullet$ What do we have to do here?
Ans: We need to identify the related addition equation for the given subtraction equation.

Say: Addition and subtraction are the opposites of each other. You can undo an addition through subtraction, and you can undo a subtraction through addition.

Ask:
$\bullet$ How do we find the difference between two numbers?
Ans: By subtracting the smaller number from the bigger number.
$\bullet$ How do you find the total of two numbers?
Ans: By adding the two smaller numbers to get a bigger number.
$\bullet$ Using the same three numbers, i.e., $3,5$ and $8,$ what addition equation can be framed?
Ans: $3+5=8$ and $5+3=8$
$\bullet$ Which of these equations is used in the given options?
Ans: $5+3=8$

Hence, Option C is correct.

WB: If required, use the whiteboard to represent the bigger and smaller number as shown and write the related addition and subtraction equations.


Probing Question:
Q. Is $3+5=8$ also a related addition equation to $8–3=5$ ?
A. Yes
