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 reallife 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.
Subject: English Language Arts (4), or Mathematics (3  4), or Technology Education (3  5) Title: Abundant Area
Description: This is an inquiry and technologybased lesson that allows students to discover the relationship between perimeter and area. Students apply problemsolving strategies to solve the reallife problem posed in this lesson. This lesson may easily be divided into sections and completed over several days if needed.

Description: This collection of Web links, reviewed and presented by Illuminations, offers teachers and students information about and practice in concepts related to arithmetic. Users can read the Illuminations Editorial Board's review of each Web site, or choose to link directly to the sites. Thinkfinity Partner: Illuminations Grade Span: K,1,2,3,4,5,6,7,8,9,10,11,12
Subject: Mathematics 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 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. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: Interactive Geometry Dictionary: Areas in Geometry
Add Bookmark
Description: This student interactive, from Illuminations, demonstrates how to find the area of three common shapes. Interactive investigations demonstrate finding the area of a rectangle, parallelogram, and triangle. Thinkfinity Partner: Illuminations Grade Span: 3,4,5,6,7,8
