### Product Description:

Using the “Simplify Fractions” Notebook file, ask students to think about what a fraction is, what is meant by simplest form, and what they think a factor is. Encourage them to use vocabulary such as numerator and denominator. Record their responses on the Notebook pages and discuss any misconceptions!
Complete with a teacher's page PDF, a "Dice Template" reproducible, and a launch-and-learn Notebook file, this mini-lesson helps to achieve the following learning objectives:
• Simplify fractions by canceling common factors.

## Teaching Tip:

This mini-lesson meets the following Common Core State Standards for Mathematics:4.NF.1: Explain why a fraction a/b is equivalent to a fraction (n x a) / (n x b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.4.NF.4a: Understand a fraction a/b as a multiple of 1/b.6.NS.4: Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12.This mini-lesson also meets the following NCTM Standards:• Develop understanding of fractions as parts of unit wholes, such as parts of a collection, as locations on number lines, and as divisions of whole numbers.• Recognize and generate equivalent forms of commonly used fractions, decimals, and percents.
