12.a, 12.b

Use a visual fraction model (area model, set model, or linear model) to show (a/b) × q and create a story context for this equation to interpret the product as a parts of a partition of q into b equal parts.
Use a visual fraction model (area model, set model, or linear model) to show (a/b) × (c/d) and create a
story context for this equation to interpret the product. 
Arkansas Academic Standards:
5.NF.B.4.A

Interpret the product (a/b) × q as a parts of a partition of q into b equal parts; equivalently, as the result of a sequence of operations a × q ÷ b
For example: Use a visual fraction model to show (2/3) × 12 means to take 12 and divide it into thirds (1/3 of 12 is 4) and take two of the parts (2 × 4 is 8), so (2/3) × 12 = 8, and create a story context for this equation. Do the same with (2/3) × (4/5) = 8/15. (In general, (a/b) × (c/d) = ac/bd.).

5.NF.4.a

Interpret the product (a/b) × q as a parts of a partition of q into b equal parts, equivalently, as the result of a sequence of operations a × q ÷ b.

Tennessee Academic Standards:
5.NF.B.4.a

Interpret the product a/b × q as a × (q ÷ b) (partition the quantity q into b equal parts and then multiply by a). Interpret the product a/b × q as (a × q) ÷ b (multiply a times the quantity q and then partition the product into b equal
parts). For example, use a visual fraction model or write a story context to show that 2/3 × 6 can be interpreted as 2 × (6 ÷ 3) or (2 × 6) ÷ 3. Do the same with 2/3 × 4/5 = 8/15. (In general, a/b × c/d = ac/bd.)
