We're winding down.
In Part 1, rectangle A shows 2 equal parts. What fraction is each part of the whole?
What happens to the denominator of our fractions as the number of parts increases?
It gets bigger.
Look at rectangle C. The unit fraction is shaded. What is the numerator of any unit fraction?
1
Look at model E. Each rectangle is 1 whole. What fraction is each part of the model?
In Part 2, which number line shows the whole number 4 correctly? Why?
C; it starts numbering at 0, there are four spaces between 0 and 4, and the lengths between the hash marks are spaced equally.
What is wrong with number line A?
The lengths between hash marks are not equal.
What is wrong with number line B?
Since there are 3 lengths from 0, the point labeled 4 actually represents the number 3.
On number line C, how many equal lengths are there from 0 to the point marked?
There are 4 equal lengths. This is why the point represents the number 4.
