Paper+Folding

**Paper Fold for Fractions**

**Content** Paper folding can be used to teach fractions.

**Grade Level** This is grade level appropriate from any students working on fractions. Specific to secondary this method is great for multiplying fractions.

**Curriculum Standards** M.S.7.1 Number and Operations Through communication, representation, reasoning and proof, problem solving, and making connections within and beyond the field of mathematics, students will
 * demonstrate understanding of numbers, ways of representing numbers, and relationships among numbers and number systems,
 * demonstrate meanings of operations and how they relate to one another, and
 * compute fluently and make reasonable estimates.

**Description of Practices** Students can use printer paper to fold into the number found in a denominator of a fraction. As a representation of the numerator of the faction, student can shade using pencils or crayons. This strategy can be used in a variety of different ways to show equivalent fractions, multiplying fractions, etc. The example link at the bottom does a great job explaining how you can multiply fractions by using paper folding.

**Implementation Considerations** This would be best for students to try on an individual basis. I would suggest modeling the method first and then having each student apply it on their own so they get the hands on knowledge.
