## Common Core State Standards for Mathematics

Grade(s) 5 resources related to the following standard:
Number and Operations—Fractions
Apply and extend previous understandings of multiplication and division to multiply and divide fractions.
7. Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.
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?

Twenty-eight lesson plans make up this research-based fourth- through sixth-grade fraction and decimal curriculum, covering through addition and subtraction of decimals, and multiplication and division of fractions. It includes a teacher guide with theoretical framework and instructions and templates for making manipulatives, as well as suggestions for using the lessons with English-language learners (ELL). The Rational Number Project is an NSF-funded multi-university research project.

This game requires students to divide the unit into fractions in order to distribute the proper laser power to the space creatures. Each level begins with a laser with a value of 1 that must be divided into several parts (from 1/2 to 11/24). The first few levels simply show how to redirect the laser, and then each level builds to more complicated fractions. The user may play the game straight through or choose a level of difficulty.

This webpage contains sample items and performance tasks from the Smarter Balanced assessment system in mathematics as well as English LA/Literacy. They are intended to help teachers, administrators, and policymakers implementing the Common Core State Standards (CCSS) prepare for next-generation assessments and plan the required shifts in instruction. Sample items and tasks can be viewed by grade band (grades 3-5, 6-8, and high school) or content focus. They showcase the variety of item types, including technology-enhanced items and performance tasks, that will be included in the assessment system. A drop-down tab provides information on each item, including grade level, CCSS alignment, and a scoring rubric for performance tasks.

This 4-page document (pdf) explains the intent, development and benefits of the CCSS. It addresses the Standards for Mathematical Practice and provides sample fractions problems to illustrate the grade 5 content standards. The article discusses assessment and implementation, and offers suggestions for parent involvement. It is available in English and Spanish.

Grade Level: K, 1, 2, 3, 4, 5
These videos focus on specific standards and include examples/illustrations geared to clarify the meaning of the individual standard rather than to be a guide on how to teach it. There is an introductory video for the collection; the videos are organized by grade level and can be downloaded as well as viewed online.

Grade Level: K, 1, 2, 3, 4, 5
This 88-page document addresses the meaning of the Common Core State Standards for teaching fractions in grades 3-7. For each grade level the specific standards that are addressed are listed, followed by a detailed explanation of what the standards mean, including visual models, and any misconceptions teachers or students might have about how specific standards apply to fractions in the CCSS.
