**Title:** Angles in the Mix

**Description:**
In this lesson, students will observe art paintings for angles - straight, right, obtuse, and acute. Using digital cameras, students will find "art" in their environment, which displays those same types of angles. They will use their photos to create a Photo Story describing the angles in their environmental art and share it with the class. Lastly, students will choose one of their photos to paint and label the angles found in their art.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.

**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.
