and then divided each of those sections into 2 equal
parts. Mark says ſ = 3 is į
Is his answer correct? Explain why or why not.

Answer 1

No, he is incorrect. Using a number line to model thirds means that each space that is 1/3 should be divided into 3 parts, not 2 parts. 6 parts divided into 3 groups gives 2 parts out of 9 parts total, so the answer is 2/9.
