ALEX Lesson Plans
Subject: Mathematics (4  5) Title: Clock Fractions
Description: Students find fractions that represent the rotation of one hand around a clock face. They learn what equivalent fractions are and how to find them. This leads to an understanding of simplifying fractions once students start to add fractions together. Finally, students will use these fractions to add them together to find the total movement around the clock.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: Mathematics (5), or Technology Education (6  8) Title: Introduction to Spreadsheets
Description: Students will utilize Excel or other spreadsheet software to create both text and numerical valued columns to produce a Christmas or birthday wish list.

Subject: Mathematics Title: Inch by Inch
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students use an actual ruler to represent various fractions as lengths. This lesson builds on work done in a previous lesson with nonstandard measurement as students use a standard instrument to measure a variety of items. Several pieces of literature appropriate for use with this lesson are suggested. Thinkfinity Partner: Illuminations Grade Span: 3,4,5
Subject: Mathematics,Science Title: Classroom Paper
Add Bookmark
Description: In this lesson, one of a multipart unit from Illuminations, students investigate data in connection with recyclable materials and develop plans to help the environment. Students gather and graph information about their classroom paper use over a period of several days and then interpret graphical information and use the data as a basis for future planning.

Subject: Mathematics Title: Fraction Models
Add Bookmark
Description: This student interactive, from Illuminations, explores several representations for fractions using adjustable numerators and denominators. Students can see decimal and percent equivalents, as well as a model that represents each fraction. Thinkfinity Partner: Illuminations Grade Span: 3,4,5,6,7,8
Subject: Mathematics Title: Fraction Game
Add Bookmark
Description: This student interactive, from Illuminations, simulates a flash card fraction game. Students flip cards one at a time and try to match the values to the given number lines. Thinkfinity Partner: Illuminations Grade Span: 3,4,5,6,7,8
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: 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.
