ALEX Lesson Plans Subject: Mathematics (3 - 5), or Technology Education (3 - 5) Title: \$100 Picture Description: This is a lesson where collaborative learning groups are used to explore  perimeter and area of an irregular figure using pattern blocks. This lesson should be used after students have already had some experience with finding the perimeter and area of a figure.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.Subject: Mathematics (3 - 5) Title: The Class Quilt Description: Students will design a 12 inch quilt square consisting of geometrical shapes.They must use their knowledge of fractions and polygons in order to create an exact 12" by 12" square.Students will use knowledge of area of a figure in order to create a quilt using their squares.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.Subject: Mathematics (4 - 5), or Technology Education (3 - 5) Title: Kids and Money Description: This lesson is used to show students how a bank pays interest to people who deposit money into it and charges interest to people who borrow money from it. Thinkfinity Lesson Plans Subject: 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: 3,4,5
