Subject: Mathematics (3 - 4)
Title: Students Only! No Teachers Aloud
Description: The students will be introduced to area and perimeter.The teacher will pose a real-life situation in which the students will have a chance to explore an actual section outside to determine the area and perimeter of a set location.

Subject: Arts Education (5), or Mathematics (3 - 5)
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.

Title: Perimeter and Area of a Rectangle
Digital Tool: Online Math Game
Digital Tool Description: This tool is an online game, which not only grabs the students' attention, but also enables them to enhance their knowledge and understanding of finding perimeter and area. The tool reteaches the concepts of perimeter and area and then allows students to practice with using measurement and formulas to find the perimeter and area.

Area Explorer
http://www.shodor.or...
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.

Subject: Mathematics
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.
