5.NF.A
Use equivalent fractions as a strategy to add and subtract fractions. (5.NF.A.1)
5.NF.B
Apply and extend previous understandings of multiplication and division. (5.NF.B.3)

Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.
MP5.
Use appropriate tools strategically.
MP6.
Attend to precision.

Students find and represent equivalent fractions using fraction circle pieces, number lines, and symbols. The equivalent fraction with the smallest possible numerator and denominator is the simplest form of the fraction. Students use fraction circle pieces and number lines to find the simplest form of fractions. They also apply divisibility rules and common factors to reduce fractions to lowest terms numerically.
