Title: "Polly"gon Pockets
Description:
In this lesson, students will explore the attributes of various polygons. Students will need to be in 12 cooperative groups (one for each shape being explored). They will complete a jigsaw puzzle to discover their shape and then list the attributes they notice about it. They will create a foldable that shows each polygon, describes its attributes, and lists items in our world that use that shape. Then, the students will create a collage using either magazines and 9x12 construction paper or the Internet and Microsoft Word to create a collage of items in our world that use polygon shapes. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Standard(s): [MA2013] (5) 25: Understand that attributes belonging to a category of twodimensional figures also belong to all subcategories of that category. [5G3]
Subject: Arts Education (5), or Mathematics (3  5)

Title: Area Explorer
Description:
This activity allows the user to test his or her skill at calculating the area of a random shape. The user is given a random figure and allowed to enter a value for the area. The user is informed whether or not the answer is correct. The user may continue trying until the answer is correct. As an extension, the students may link to a chart that compares the area to the perimeter.
Standard(s): [MA2013] (3) 23: Solve realworld and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different areas or with the same area and different perimeters. [3MD8]

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 eexample from Illuminations contains an interactive version of a game that can be used in the grades 35 classroom to support students' learning about fractions. eMath Investigations are selected eexamples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The eexamples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the eexamples are natural companions to the iMath investigations.
