(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 =(na)/(nb) to the effect of multiplying a/b by 1.
jApply and extend previous understandings of multiplication and division to multiply and divide fractions.
5.NF 7. Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.1
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.
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 t<he relationship between multiplication and division to explain that 4 (1/5) = 20 because 20 (1/5) = 4.
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?
j"Geometric measurement: understand concepts of volume and relate volume to multiplication and to addition.
5.MD.5. Relate volume to the operations of multiplication and addition and solve real world and mathematical problems involving volume.
a. Find the volume of a right rectangular prism with wholenumber side lengths by packing it with unit cubes, and show that the volume is the same as would be found by multiplying the edge lengths, equivalently by multiplying the height by the area of the base. Represent threefold wholenumber products as volumes, e.g., to represent the associative property of multiplication.
b. Apply the formulas V = l w h and V = b h for rectangular prisms to find volumes of right rectangular prisms with wholenumber edge lengths in the context of solving real world and mathematical problems.
c. Recognize volume as additive. Find volumes of solid figures composed of two nonoverlapping right rectangular prisms by adding the volumes of the nonoverlapping parts, applying this technique to solve real world problems.
