Emphasis: MStandard  5.NF.3:
Interpret a fraction as division of the numerator by the denominator (a/b = a / b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie? 

Component  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. For example, use a visual fraction model to show (2/3) * 4 = 8/3, 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.) 
Component  5.NF.4.b:
Find the area of a rectangle with fractional side lengths by tiling it with unit squares of the appropriate unit fraction side lengths, and show that the area is the same as would be found by multiplying the side lengths. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas.



Component  5.NF.5.a:
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. 
Component  5.NF.5.b:
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; and relating the principle of fraction equivalence a/b = (n*a)/(n*b) to the effect of multiplying a/b by 1.


Emphasis: MEStandard  5.NF.6:
Solve real world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem. 

Component  5.NF.7.a:
Interpret division of a unit fraction by a nonzero whole number, and compute such quotients. For example, create a story context for (1/3) / 4, and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that (1/3) / 4 = 1/12 because (1/12) * 4 = 1/3. 
Component  5.NF.7.b:
Interpret division of a whole number by a unit fraction, and compute such quotients. For example, create a story context for 4 / (1/5), and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that 4 / (1/5) = 20 because 20 * (1/5) = 4. 
Component  5.NF.7.c:
Solve real world problems involving division of unit fractions by nonzero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem. For example, how much chocolate will each person get if 3 people share 1/2 lb of chocolate equally? How many 1/3cup servings are in 2 cups of raisins?
