ALEX Lesson Plans Subject: Mathematics (6) Title: Express Yourself with Patterns Description: During this lesson, the students will use growing patterns to develop an algebraic expression with understanding. The students will also learn mathematical vocabulary with the use of the newly created expression. Thinkfinity Lesson Plans Subject: MathematicsTitle: Balancing Shapes      Add Bookmark Description: In this lesson, one of a multi-part unit from Illuminations, students balance shapes using an interactive pan balance applet to study equality, essential to understanding algebra. Equivalent relationships are recognized when the pans balance, demonstrating the properties of equality.Thinkfinity Partner: IlluminationsGrade Span: 6,7,8Subject: MathematicsTitle: Pan Balance -- Expressions      Add Bookmark Description: This interactive pan balance, from Illuminations, allows students to enter and compare numeric or algebraic expressions. They can '' weigh'' the expressions they want to compare by entering them on either side of the balance, allowing them to practice arithmetic and algebraic skills, as well as to investigate the concept of equivalence.Thinkfinity Partner: IlluminationsGrade Span: 3,4,5,6,7,8,9,10,11,12Subject: MathematicsTitle: Exploration of a Balance      Add Bookmark Description: In this four-lesson unit from Illuminations, students participate in activities in which they focus on patterns and relations that can be developed from the exploration of balance, mass, length of the mass arm, and the position of the fulcrum. This unit includes an individual activity for four different levels from grade 1 to grade 8.Thinkfinity Partner: IlluminationsGrade Span: 1,2,3,4,5,6,7,8
