Question

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

• A. $6–5=4$
• B. $5–1=4$
• C. $1–5=6$
• D. $6–5=1$

Answer 1

The correct option is D $6–5=1$

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: $6$
$\bullet$ So, how many jumps are represented by the arrow from $0$ to $6$ ?
Ans: $6$
$\bullet$ How many backward jumps are made?
Ans: $5$
$\bullet$ If we take $6$ jumps forward and $5$ jumps back, what subtraction equation could be framed to show the number of jumps needed to reach the circled number?
Ans: $6–5=1$

Hence, Option C 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 backward jumps will we make to arrive at the circled number?
A. $1$
