Question

There are a total of 4 fruits, out of which $1$ is a strawberry and $3$ are cherries. What are the two subtraction equations that can be created to form the fact family of the numbers $1,3$, and $4$?

• A. $4–1=3$ and $4–3=1$
• B. $3–2=5$ and $2–3=5$
• C. $1–4=3$ and $1–3=4$
• D. $2–3=1$ and $3–2=1$

Answer 1

The correct option is A $4–1=3$ and $4–3=1$

Say : Let's read the question.

Ask:
$\bullet$ What do we have to do here?
Ans: We need to frame two subtraction equations using the numbers $1,3$, and $4$.
$\bullet$ How many fruits are there in total?
Ans: $4$
$\bullet$ How many strawberries are there?
Ans: $1$
$\bullet$ How many cherries are there?
Ans: $3$
$\bullet$ How do we find the difference?
Ans: By subtracting the smaller number from the bigger number.
$\bullet$ Using the three numbers, i.e., 1, 3, and 4, what subtraction equations can be framed?
Ans: $4–1=3$ and $4–3=1$
Hence, Option A is correct.

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


Probing Question:
Using the same three numbers, i.e., $1,3,$ and 4, what addition equations can be framed?
A. $1+3=4$ and $3+1=4$
