Question

There are a total of $7$ fruits, out of which 3 are mangoes and $4$ are bananas. What are the two addition equations that can be created to form the fact family of the numbers $3,4,$ and $7$ ?

• A. $1+2=3$ and $2+1=3$
• B. $3+1=4$ and $1+2=3$
• C. $4+3=7$ and $3+4=7$
• D. $2+2=4$ and $1+3=4$

Answer 1

The correct option is C $4+3=7$ and $3+4=7$

Say: Let's read the question.

Ask:
$\bullet$ What do we have to do here?
Ans: We have to frame two addition equations using the numbers $3,4$ , and $7$ for the total number of fruits.
$\bullet$ How many fruits are there in total?
Ans:$7$
$\bullet$ How many mangoes are there?
Ans: $3$
$\bullet$ How many bananas are there?
Ans: $4$
$\bullet$ How do we find the total?
Ans: By adding two smaller numbers to get a bigger number.
Using the three numbers, i.e., $3,4,$ and $7$, what addition equations can be framed?
Ans: $4+3=7$ and $3+4=7$
Hence, Option B is correct.

WB: Use the whiteboard to represent the bigger number and check the smaller number as shown, and write the addition equations.

Probing Question:
Using the same three numbers, i.e., $3,4$, and $7$, what subtraction equations can be framed?
A. $7–3=4$ and $7–4=3$
