Algebra

===**Students solve simple linear equations and inequalities. They interpret and evaluate expressions involving integer* powers. They graph and interpret functions. They understand the concepts of slope* and rate. Follow the links below to learn more.**===


 * [|Algebra Tiles]**- Using tiles to represent variables and constants, learn how to represent and solve algebra problem. Solve equations, substitute in variable expressions, and expand and factor. Flip tiles, remove zero pairs, copy and arrange, and make your way toward a better understanding of algebra. [[image:http://mozey.files.wordpress.com/2007/02/findx.gif align="right"]]


 * [|Balance Scales]**- This virtual manipulative allows you to solve simple linear equations through the use of a balance beam.


 * [|Line of Best Fit]**-This activity allows the user to enter a set of data, plot the data on a coordinate grid, and determine the equation for a line of best fit.


 * [|Pan Balance]**- This interactive pan balance allows numeric or algebraic expressions to be entered and compared. You can "weigh" the expressions you want to compare by entering them on either side of the balance. Using this interactive tool, you can practice arithmetic and algebraic skills, and investigate the important concept of equivalence.
