5.NF.6
About the Math
Full Standard
Solve real world problems involving multiplication of fractions and mixed numbers (e.g., by using visual fraction models or equations to represent the problem).

Learning Targets (I can)
- Represent word problems that multiply fractions and mixed numbers with physical models, drawings, and number lines.
- Write equations for word problems that multiply fractions and mixed numbers.
- Solve problems that multiply fractions and mixed numbers.
- Determine reasonableness of solutions to word problems that multiply fractions and mixed numbers using the context of the word problem (does this make sense in the problem?).
About the Math
Solving word problems with addition, subtraction, multiplication and division of fractions follow the same problem solving structures for whole number situations.
- Represent word problems that multiply fractions and mixed numbers with physical models, drawings, and number lines.
- Solve problems that multiply fractions and mixed numbers.
These word problems should represent the various problem-solving structures linked above. Students should diagram and represent problems to connect to their equations. Students should not rely on key words for finding solutions.
- Write equations for word problems that multiply fractions and mixed numbers.
Pictures and diagrams are useful for understanding problems. Students should connect them to equations. Students should then connect their equations back to the problem. In time, when appropriate, students should generate and use equations to solve their problems. Students can resort back to pictures and diagrams as needed.
- Determine reasonableness of solutions to word problems that multiply fractions and mixed numbers using the context of the word problem (does this make sense in the problem?).
Students can determine reasonableness in a variety of ways. Doing so takes a good bit of time and experience. Predicting and estimating results for comparison helps students develop a sense of reasonableness. Other strategies, including reflective self-questions, help as well. Teacher modeling and teacher self-talk help students understand the questions and thoughts they should consider.

Instructional Tasks
TASKS
These tasks can be used with small group or whole group instruction.
- A lemonade recipe serves six people and requires 2 ⅔ cup sugar. How much sugar will you need if you make the recipe to serve 9 people?
- You have a piece of paper that measures 1ft.x1ft. If you want the paper to be ¾ of it’s size in both length and width, what will be the final measurements of the paper (in inches)?
- The community pool measures 12 ⅜ feet x 16 ⅔ feet. John wants to build a pool that is 1 ¾ times the size of the community pool- in length and width. What will be the dimensions of your John’s pool?
- India and Jess have been given a bag of individually wrapped chocolates. If India takes ¼ of the chocolates and Jess takes ⅕ of the chocolates, how many chocolates might have been in the bag and how many might still be in the bag?
- Write a story problem with two fractions with a product greater than 1.
SLIDE-BASED TASKS
These links are HCPSS created instructional tasks. These tasks are provided in Google slides. These tasks should be used for inspiration and resources, but instruction should start with students having the opportunity to engage with the math first (often involving physical and/or visual models) followed by discussion and explicit instruction to ensure student understanding.
Module 6 • Multiplying Fractions
Multiplying Fractions by Fractions (no mixed numbers):
Module 7 • Multiplying and Dividing Fractions
