Question

Out of $6$ items in a pencil box, $2$ are colored pencils and 4 are crayons. If $2+4=6$ is one of the equations from the fact family of the numbers $2,4,$ and $6,$ what are the remaining three equations that can be formed?

• A. $4+2=6,6–2=4,6–4=2$
• B. $2+6=4,4–6=2,2–6=4$
• C. $7–1=6,1–7=6,6+1=7$
• D. $6–3=3,3+3=6,6–3=3,$

Answer 1

The correct option is A $4+2=6,6–2=4,6–4=2$

Say: Let us read the question and observe the image.

Ask:
$\bullet$ How many items are there in all?
Ans: $6$
$\bullet$ How many are colored pencils?
Ans: $2$
$\bullet$ How many are crayons?
Ans: $4$
$\bullet$ What is the given equation framed with the numbers $2,4,$ and $6$ ?
Ans: $2+4=6$
$\bullet$ How many more addition equations can be formed with these three numbers other than the one given?
Ans: $1$ more
$\bullet$ What will the addition equation be?
Ans: $4+2=6$
$\bullet$ How many subtraction equations can be formed?
Ans: $2$
$\bullet$ What will be the equations?
Ans: $6–4=2$ and $6–2=4$
$\bullet$ What do we call these four equations together?
Ans: Fact family
Hence, option B is the correct answer.

WB: Use the whiteboard to draw the number frame and write the equations.
