Title: Measuring Angles 
Description: This lesson is designed to teach students to measure angles with a protractor. The student will be taught how to read the protractor correctly by using either the top or bottom set of numbers. The lesson will reinforce classifying angles as acute, right, and obtuse. The student will sketch angles given a specified measure. This lesson results from the ALEX Resource Gap Project.

Subject: Mathematics (4)
Title: Pizza Problems: An Angle Investigation
Description: This investigative lesson allows students to identify angle measurements as part of a larger angle. Students will deconstruct 180 degree angles into equal parts.  This is a College- and Career-Ready Standards showcase lesson plan.

Title: Communicating about Mathematics Using Games: Playing Fraction Tracks      Add Bookmark
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.
