Standard: CC.2.1.5.C.2, M05.A-F.2.1.1, M05.A-F.2.1.2, M05.A-F.2.1.3, M05.A-F.2.1.4 Apply and extend previous understandings of multiplication and division to multiply and divide fractions. Solve word problems involving division of whole numbers leading to answers in the form of fractions (including mixed numbers). Multiply a fraction (including mixed numbers) by a fraction. Demonstrate an understanding of multiplication as scaling (resizing). Example 1: Comparing the size of a product to the size of one factor on the basis of the size of the other factor without performing the indicated multiplication. Example 2: Explaining why multiplying a given number by a fraction greater than 1 results in a product greater than the given number (recognizing multiplication by whole numbers greater than 1 as a familiar case); explaining why multiplying a given number by a fraction less than 1 results in a product smaller than the given number. Divide unit fractions by whole numbers and whole numbers by unit fractions.

LEARNING SCALE
With help, the student demonstrates partial success at 2.0 and 3.0.
I can:
Recognize or recall specific vocabulary, such as: mixed fraction, improper fraction, reduce, remainder, and scaling.
Perform basic processes, such as: explain how to compare the size of a product to the size of one factor; explaining multiplication as scaling; explain how to reduce an improper fraction; explain algorithms for multiplying or dividing fractions and whole numbers.
