Solution
The correct option is A4+2=6,6–2=4,6–4=2 Say: Let us read the question and observe the image.
Ask: ∙ How many items are there in all?
Ans: 6 ∙ How many are colored pencils?
Ans: 2 ∙ How many are crayons?
Ans: 4 ∙ What is the given equation framed with the numbers 2,4, and 6 ?
Ans: 2+4=6 ∙ How many more addition equations can be formed with these three numbers other than the one given?
Ans: 1 more ∙ What will the addition equation be?
Ans: 4+2=6 ∙ How many subtraction equations can be formed?
Ans: 2 ∙ What will be the equations?
Ans: 6–4=2 and 6–2=4 ∙ 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.
