**Title:** Introduction to Spreadsheets

**Description:**
Students will utilize Excel or other spreadsheet software to create both text and numerical valued columns to produce a Christmas or birthday wish list.
**Standard(s): **

[MA2015] (5) 17: Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions. (Students able to multiply fractions in general can develop strategies to divide fractions in general by reasoning about the relationship between multiplication and division. However, division of a fraction by a fraction is not a requirement at this grade.)

**Title:** Another Look at Fractions of a Set

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students identify fractions in real-world contexts from a set of items that are not identical. Students develop skills in problem-solving and reasoning as they think about their set and how to create new sets given specific fractional characteristics.
**Standard(s): **

[MA2015] (5) 24: Represent real-world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation. [5-G2]

**Title:** Inch by Inch

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students use an actual ruler to represent various fractions as lengths. This lesson builds on work done in a previous lesson with nonstandard measurement as students use a standard instrument to measure a variety of items. Several pieces of literature appropriate for use with this lesson are suggested.
**Standard(s): **

[MA2015] (5) 19: Make a line plot to display a data set of measurements in fractions of a unit (^{1}/_{2}, ^{1}/_{4}, ^{1}/_{8}).
Use operations on fractions for this grade to solve problems involving information presented in line plots. [5-MD2]

**Title:** Classroom Paper

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students investigate data in connection with recyclable materials and develop plans to help the environment. Students gather and graph information about their classroom paper use over a period of several days and then interpret graphical information and use the data as a basis for future planning.

**Title:** Communicating about Mathematics Using Games: Playing Fraction Tracks

**Description:**
Mathematical games can foster mathematical communication as students explain and justify their moves to one another. In addition, games can motivate students and engage them in thinking about and applying concepts and skills. This e-example from Illuminations contains an interactive version of a game that can be used in the grades 3-5 classroom to support students' learning about fractions. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.
