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 1-25 or 1-100 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.

Title: Exploration of a Balance
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.

Title: Balancing Shapes
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.

Please Excuse My Dear Aunt Sally As She Makes the Number 24
http://www.fisme.sci...
The students get 4 numbers presented on a number card. With these numbers and an interactive calculator, students try to compute the number 24. Students use order of operations to solve a numerical expression that equal 24.

Virtual Balance Beam: Linear Equations
http://nlvm.usu.edu/...
The National Library of Virtual Manipulatives has created a virtual manipulative that allows students to solve linear equations through the use of a balance beam. Unit blocks represent numbers and X boxes represent the unknown X. The manipulatives are placed on the pans of a balance beam. Once the beam balances to represent the given linear equation, the student can choose to perform any operation, as long as the student does the same thing to both sides, thus keeping the beam balanced.

Title: Pan Balance -- Expressions
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.
