Question

Out of the total fruits, $6$ are melons and the number of apples is $3$ more than the number of melons. Which of the following options shows the correct equations that can be created to form the fact family of the number of fruits?

• A. $6+9=15,9+6=15,15–6=9,15–9=6$
• B. $6+3=9,3+6=9,6+9=15,9+6=15$
• C. $6+9=15,9+6=15,9–6=3,6–3=3$
• D. $6+9=3,9+3=6,9–6=3,9-3=6$

Answer 1

The correct option is A $6+9=15,9+6=15,15–6=9,15–9=6$

Say: Let’s read the question.

Ask:
$\bullet$ What do we have to do here?
Ans: We need to frame the fact family equations using the number $6,$ the number of apples, and the total number of fruits.
$\bullet$ How many melons are there?
Ans: $6$
$\bullet$ How many apples are there?
Ans: $3$ more than the number of melons.
$\bullet$ How many apples is that?
Ans: $6+3=9.$ There are $9$ apples.

Say: We now know the number of apples, let’s find the total number of fruits to frame the equations that can be created to form the fact family of the number of fruits.

Ask:
$\bullet$ How will we find the total number of fruits?
Ans: By adding the number of melons, i.e., $6$ and the number of apples, i.e., $9.$
$\bullet$ What equation will be framed?
Ans: $6+9=15$
$\bullet$ So, how many fruits are there in total?
Ans: $15$

Say: Now that we know all the three numbers needed to frame fact family equations, let’s frame the remaining addition and subtraction equations.

Ask:
$\bullet$ Since we already framed the equation $6+9=15,$ what other addition equation can we frame?
Ans: $9+6=15$
$\bullet$ Using the same three numbers, i.e., $6,9,$ and $15$, what subtraction equations can be framed?
Ans: $15–6=9$ and $15–9=6$

Hence, Option A is correct.

WB: If required, use the whiteboard to represent the number of melons and the number of apples as shown to find the total number of fruits, and write the related addition and subtraction equations.
