We will be regularly adding new episodes (lessons and practice) to Amplify Fractions through April 2018. For reference, here is how the current slate of content maps to educational standards:

Texas Essential Knowledge and Skills (TEKS)

Here is a more detailed look at how the first 15 episodes align with Common Core Standards.

The first strand reviews the concept of partitive division. The first episode, **Fair Sharing**, tackles equipartitioning of discrete sets of objects and relates it to division. The second episode, **Dividing Length**, similarly explores equiparitioning of linear arrays of discrete objects.

Together, these two episodes map to standards on understanding multiplication and division:

The next strand of episodes dives into various representations of unit fractions, including rectangular area models (**Dividing the Whole**), circular area models (**Circles**), other symmetric area models (**Shapes**), and one-dimensional lengths (**Length**). The final episode in this strand (**Outside the Whole**) relates unit fraction amounts to *other unit wholes*, not necessarily one that was equipartitioned.

The next strand covers non-unit fractions, including: proper fractions (**Part-Whole**), **Improper Fractions**, **Mixed Numbers**, and non-unit fractions that are **Outside the Whole**. The strand also includes an episode that explores the relationship between **Fractions and Division**, a more advanced concept that is worth seeing early on. Taken together, these episodes map to some of the "meatiest" standards:

The next strand of content completes the first set of 15 episodes. These episodes involve placing fractions on the number line according to their **Distance from Zero**, strategies for locating **Fractions on the Number Line**, as well as for **Mixed Numbers on the Number Line**. These episodes map to the following standards:
