Question

Sandy collects $7$ butterfly stickers. How many more stickers does she need to collect to have $13$ butterfly stickers? Identify the addition equation that is framed using the same numbers as those in the equation given below.
$13–7=$ __

• A. $6;13+6=19$
• B. $6;7+6=13$
• C. $6;7+6=12$
• D. $7;7+7=14$

Answer 1

The correct option is B $6;7+6=13$

Say: Let's read the question.

Ask:
$\bullet$ What do we have to do here?
Ans: We have to find the number of butterfly stickers Sandy needs to collect.
$\bullet$ How do we find the difference between two numbers?
Ans: By subtracting the smaller number from the bigger number.
$\bullet$ What is the bigger number?
Ans: $13$
$\bullet$ What is the smaller number?
Ans: $7$
$\bullet$ What equation will be framed?
Ans: $13–7=6$
$\bullet$ So, how many more butterfly stickers does Sandy need?
Ans: $6$

Say: Now let us identify the addition equation using the same numbers.

Ask:
$\bullet$ How do we find the total of two numbers?
Ans: By adding the two smaller numbers to get a bigger number.
$\bullet$ Using the same three numbers $6,7,$ and $13,$ what addition equations can be framed?
Ans: $6+7=13$ or $7+6=13$
$\bullet$ Which of these equations is used in the given options?
Ans: $7+6=13$

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.
