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. Thinkfinity Lesson Plans Subject: MathematicsTitle: Another Look at Fractions of a Set      Add Bookmark Description: In this lesson, one of a multi-part unit from Illuminations, students identify fractions in real-world contexts from a set of items that are not identical. Students develop skills in problem-solving and reasoning as they think about their set and how to create new sets given specific fractional characteristics.Thinkfinity Partner: IlluminationsGrade Span: 3,4,5Subject: MathematicsTitle: Inch by Inch      Add Bookmark Description: In this lesson, one of a multi-part 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: IlluminationsGrade Span: 3,4,5Subject: Mathematics,ScienceTitle: Classroom Paper      Add Bookmark Description: In this lesson, one of a multi-part 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.Thinkfinity Partner: IlluminationsGrade Span: K,PreK,1,2,3,4,5Subject: MathematicsTitle: 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: IlluminationsGrade Span: K,1,2,3,4,5,6,7,8,9,10,11,12Subject: MathematicsTitle: 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 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.Thinkfinity Partner: IlluminationsGrade Span: 3,4,5Subject: MathematicsTitle: 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: IlluminationsGrade Span: 3,4,5,6,7,8Subject: MathematicsTitle: 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: IlluminationsGrade Span: 3,4,5,6,7,8
