Section A: Practice Problems Introduction to Fractions
In this section, we learned how to partition shapes into halves, thirds, fourths, sixths, and eighths, and how to describe each of those parts in words and using a number.
The numbers we use to describe these equal-sized parts are fractions.
A fraction like

Fractions that refer to only one of the equal parts in a whole— like
We learned that the bottom part of the fraction tells us how many equal parts we partitioned the whole into. The top part of the fraction tells us how many of the equal parts are being described.
