The correct option is
C 19−12=7Solution: Option C
Say: The total number of forks and spoons is given.
Ask:
What is the total number of spoons and forks?
Ans:
19
How many more spoons are there than the forks?
Ans:
5
What do we need to find here?
Ans: Number of forks
How can we find the number of forks?
Ans: By subtracting number of spoons from the total number, i.e., total number – number of spoons = number of forks.
Which equation from options will help us find out the number of forks?
Ans: Option C, i.e.,
19–12=7
Why do you think so?
Ans: The difference in the equation i.e., number of forks is
7, and the smaller number in the equation, i.e., number of spoons is
12. Here, we can say that the number of spoons is
5 more than the number of forks because
12 is
5 more than 7, i.e.,
7+5=12.
What is the number of forks?
Ans:
7
How is the subtraction equation written here?
Ans: By subtracting the smaller number, i.e.,
12 from the greater number, i.e.,
19 we get a difference of
7.
Hence, Option C is correct.
WB: If required, use the whiteboard to represent the total number of forks and spoons using counters on a number frame. Then cross out the number of spoons as shown and write the subtraction equation.
