Question

When using a number line to model thirds, how should each space that represents 1/3 be divided?

A) Into 2 parts
B) Into 3 parts
C) Into 4 parts
D) Into 9 parts

Answer 1

On a number line, to model thirds, you do not divide each third further; each marked section already represents one third.

Step-by-step explanation:

When using a number line to model thirds, each space that represents 1/3 should not be divided into any smaller parts to accurately represent a third. The correct answer is that you do not have to further divide each third because it is already a representation of one third. The number line would have marks that indicate the size of each third, without further division within those thirds.

This is analogous to slicing a pie into three equal pieces where each piece represents one third of the pie; you wouldn't need to slice it further to show it's a third.
