ALEX Lesson Plans
Subject: Mathematics (5  7), or Technology Education (6  8) Title: Ping Pong Madness
Description: In this lesson, students will use their knowledge of 3D shapes to create packages for ping pong balls. They must create small, medium and large packages that are cost effective and stack easily. They will make nets of the their packages and find the volume and surface area of each. Students will present the information using a multimedia presentation and a spreadsheet software. This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMSU Project.
Subject: Mathematics (3  5), or Science (3), or Technology Education (3  5) Title: The Water Cycle
Description: During this lesson, students will learn that water is constantly being recycled through the atmosphere and how this affects us. Students will explore the water cycle on the Internet. Students create different types of weather situations to see how the water cycle works. Mathematics skills will be used to determine results from the observations.

Subject: Mathematics Title: Getting to Know the Solids
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students use an online, interactive activity to analyze characteristics and properties of threedimensional geometric shapes; develop mathematical arguments about geometric relationships; and use visualization, spatial reasoning, and geometric modeling to solve problems. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics Title: Another Look at Fractions of a Set
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students identify fractions in realworld contexts from a set of items that are not identical. Students develop skills in problemsolving and reasoning as they think about their set and how to create new sets given specific fractional characteristics.

Subject: Mathematics Title: Cubes
Add Bookmark
Description: This student interactive, from Illuminations, helps students explore the volume of a box based on the amount of unit cubes that can fit inside of it. They are prompted to come up with a rule for determining the volume of a box when its width, depth, and height are known. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics,Science Title: Collecting the Rays
Add Bookmark
Description: In this lesson, from Illuminations, students explore how variations in solar collectors affect the energy absorbed. They make rectangular prisms that have the same volume but different linear dimensions. Students investigate relationships among the linear dimensions, the area, and the volume of rectangular prisms.

Subject: Mathematics Title: Number and Operations Web Links
Add Bookmark
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: Finding Products
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students examine the role of commutativity and the multiplicative identity, play a multiplication game, and explore products where one of the factors is 6. They also create a personal multiplication chart. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
