In this 45-day module, students build on their Grade 3 work with unit fractions as they explore fraction equivalence and extend this understanding to mixed numbers. This leads to the comparison of fractions and mixed numbers and the representation of both in a variety of models. Benchmark fractions play an important part in student's ability to generalize and reason about relative fraction and mixed number sizes. Students then have the opportunity to apply what they know to be true for whole number operations to the new concepts of fraction and mixed number operations.

In Module 3, student's understanding of addition and subtraction of fractions extends from earlier work with fraction equivalence and decimals. This module marks a significant shift away from the elementary grades' centrality of base ten units to the study and use of the full set of fractional units from Grade 5 forward, especially as applied to algebra.

1. Have the students bring a Math graphing problem that they have been working on in class.  **This will take some coordination with their homeroom teacher in order to work! or present a simple graphing problem for them to solve.  It needs to have 3-4 variables. This is so that they can use 3-4 coordinating colors of yarn for their design.In this lesson, we will translate the bar graph chart into a horizontal graph design.  Use the numbers to represent rows of weaving. For example, if a 5 is represented in the information then color in a section of rows on the graph paper to represent 5 rows that will be woven in that color. Tell the students to use the same colors that they have on their math bar graph, when creating their graph for weaving so that there is less confusion. 

This series of Google Slides was developed as an introductory lesson to adding fractions with unlike denominators. It is intended to help students build their conceptual understanding of why they will use the Least Common Denominator later on in the unit. Also, because this is meant as an introductory lesson, it does not simplify answers. This product is intended to be used by the teacher in the front of the class while students have their own sets of fraction strips at their seats.

Using benchmark fractions, this lesson helps students use conceptual understanding to add and subtract fractions with unlike denominators.
