## 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.

## Solving One-step First-degree Equations

Watch the examples in the "Introduction", then select the following from the "Algebra Tile Practice" section.

• x + a = b
• x - a = b
• ax = b
• x/a = b

## 4 Methods for Solving Linear Questions

There are a variety of ways to solve linear equations.  Select the buttons below, then study the four methods displayed:

## ax = b       x/a = b       a/x = b

• Click to get a randomly created one-step equation problems.
