**Title:** Line of Symmetry

**Description:**
During this lesson, students will use a hands-on method to identify lines of symmetry. Each student will create individual lines of symmetry by using their name. Creations are unique and individualized for each student. Students will also learn more details about lines of symmetry by navigating the Internet. Students will do online activities to reinforce what they have learned about lines of symmetry.
**Standard(s): **

[MA2015] (5) 26: Classify two-dimensional figures in a hierarchy based on properties. [5-G4]

**Subject:**English Language Arts (6), or Mathematics (4 - 5), or Technology Education (6 - 8)

**Title:** Finding Lines of Symmetry

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students identify and create lines of symmetry and congruent figures. They explore these concepts with paper cutting and modeling on a geoboard.

**Title:** Planning a Mini-quilt

**Description:**
In this lesson, one of a multi-part unit from Illuminations, students create a quilt using three transformations (reflection, rotation, and translation) and then investigate the ways shapes can be colored to show one-half and one-fourth. Several pieces of literature appropriate for use with this lesson are suggested.

**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.
