Algebra Tile Review

Algebra tiles have a variety of other names: algetiles, math tiles, and virtual tiles.  Algebra tiles can help you visualize equivalent algebraic expressions and/or equations.  Many of the real tiles have a positive and a negative side. The virtual algebra tiles activities will use multi-coloured positive tiles. The reverse (negative) side of each of these tiles is red. It helps to understand that negative tiles have one positive and one negative dimension.

Some algebra kits use black tiles for positive areas and red for the flip (negative) sides. Click the "Black/Red Tiles" button for additional information.

Review of 1-step and 2-step Linear Equations

Linear Equations 1

ax + b = cx + d

There are several example solutions using algebra tiles given in the "Examples".

The "Algebra Tiles Practice" includeds question generators for various linear equations. Select "ax + b = cx + d" to generate Linear Equations 1 examples. You may use the virtual tiles provided to generate a solution. The step buttons provided on the right show sample solutions as well.

Let's study how these tiles can be used to solve equations.

 

4 Methods for Solving Linear Questions

There are a variety of ways to solve linear equations.  Four methods for each type of linear equation is included below:

ax + b = cx + d

Enter an equation along with the variable you wish to solve it for and click .

A sample has been entered for you.  Get additional examples by clicking .

Other internet sites that provide algebraic models to help you learn to solve equations.  Launch the following site, and enter expressions on either side of the "=" sign below "TYPE YOUR PROBLEM".   Enter the variable you are solving for below "TYPE THE VARIABLE TO SOLVE FOR".  Click "SOLVE".

 

Two-Step Linear Equation Solver

This equation solving applet will allow you to enter your own equation and complete the steps to solve it.

Be patient.  The applet will take a few moments to load.

If you have difficulties, you can cut and paste the question you are working on and paste it into the previous calculator.

Equation Calculator

ax + b = cx + d

The "Equation Calculator" will generate equations or allow you to enter your own. 

  • Click "Example" to generate an equation.  The steps and solution will be provided.

  • After entering an equation of the form ax + b = cx + d, click "Solve" to see the steps and solution Change the coefficients and constants and see the changes in the steps required to reach the solution.  If you choose this option make sure you choose the appropriate variable in the drop down menu.
