Question

With the help of the given number line, select the correct subtraction equation

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

Answer 1

The correct option is D $4–1=3$

Say: Let's read the question and observe the number line.

Ask:
$\bullet$ What do we have to do here?
Ans: We need to identify the equation for the given number line.
$\bullet$ Until what number does the bigger arrow extend?
Ans: $4$
$\bullet$ So, how many jumps are represented by the arrow from $0$ to $4$?
Ans: $4$
$\bullet$ How many backward jumps are made?
Ans: $1$
$\bullet$ If we take $4$ jumps forward and $1$ jump back, what subtraction equation could be framed to show the number of jumps needed to reach the circled number?
Ans: $4–1=3$

Hence, Option A is correct.

WB: If required, use the whiteboard to draw a number line and draw arrows to identify the number of jumps required to reach the circled number, and write the subtraction equation as shown.


Probing Question:
Q. How many more backward jumps will we make to arrive at the circled number?
A. $3$

Q. If we subtract $3$ from $4,$ what number will we get?
A. $4–3=1$
