### PRODUCT DESCRIPTION

The common core incorporates problem solving in the Standards for Mathematical Practice and throughout the standards in almost every concept! If students are able to complete all computations correctly but are unsure of when and how to apply them, they are not proficient in those areas. For that reason, I have included problems with all operations in the same lesson.

I consider these to be application problems more than true problem solving, because they are all applications of a specific concept: fractions.

In every problem there is either extra information or students need to infer information, which promotes critical thinking! (An example of an inference would be to include Jill and 3 friends as 4 people.)

I often use these and have students work in small groups or with a partner. If you want students to work individually, you will just need to make extra copies of the task cards. That works well, too. For a class working independently, I would make 3 sets.

Here is what you will find included:
blank directions (for personalized use)
solutions

Thanks again so much! I hope you find these helpful!

CCSS.MATH.CONTENT.5.NF.A.2
Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. For example, recognize an incorrect result 2/5 + 1/2 = 3/7, by observing that 3/7 < ½.

CCSS.MATH.CONTENT.5.NF.B.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 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?

CCSS.MATH.CONTENT.5.NF.B.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.

CCSS.MATH.CONTENT.5.NF.B.7.C
Solve real world problems involving division of unit fractions by non-zero 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 1/3-cup servings are in 2 cups of raisins?
