Question

There are $15$ flowers and $9$ bees. Identify the equation to find how many fewer bees there are than flowers, and the addition and subtraction equations.

• A. $15+9=24,9+15=24,24–9=15,24–15=9$
• B. $9–6=3,6–9=3,9+6=15,6+9=15$
• C. $15–9=6,15–6=9,9+6=15,6+9=15$
• D. $3+6=9,6+3=9,9=3=6,9–6=3$

Answer 1

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

Say: Let's read the question.

Ask:
$\bullet$ What do we have to do here?
Ans: We need to identify the related addition and subtraction equations to find how many fewer bees there are than flowers.
$\bullet$ How many flowers are there?
Ans: $15$
$\bullet$ How many bees are there?
Ans: $9$
$\bullet$ How do we find the difference?
Ans: By subtracting the smaller number, i.e., $9$ from the bigger number, i.e., $15$.
$\bullet$ What equation will be framed?
Ans: $15–9=6$
$\bullet$ What if we knew how many fewer bees there were fewer than the number of flowers, i.e., $6$ and had to find the number of bees? What equation would we frame then?
Ans: $15–6=9$
$\bullet$ Using the same three numbers, i.e., $6,9,$ and $15,$ what addition equation can be framed?
Ans: $9+6=15$ and $6+9=15$

Hence, Option B 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.
