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.
Subject: Mathematics (6  7) Title: Order Among Chaos
Description: This lesson is designed to assist students not only in using the order of operations, but also experimenting with how grouping and ordering affects answers. In groups as teams, the students will compete while finding algebraic expressions using only the numbers 1, 2, 3, and 4, as well as all operations including exponents and grouping symbols, to find a desired integer result. To gain points, the value of each formed expression must be from the set of integers 125 or 1100 depending on time constraints. They should attempt to get an expression with each of the listed integers required. Modeled examples are embedded in the directions slide show so the students are instructed in the process of the competition.

Subject: Mathematics Title: Balancing Shapes
Add Bookmark
Description: In this lesson, one of a multipart 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: Illuminations Grade Span: 6,7,8
Subject: Mathematics Title: 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: Illuminations Grade Span: 3,4,5,6,7,8,9,10,11,12
Subject: Mathematics Title: Exploration of a Balance
Add Bookmark
Description: In this fourlesson 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: Illuminations Grade Span: 1,2,3,4,5,6,7,8
