What are Algebra Tiles?

• They are useful manipulatives for a number of
  algebraic operations
• Adding, subtracting, multiplying, dividing
  polynomials
• Factoring trinomials
• Solving equations by completing the square
• Also helpful for learning negative and positive
  numbers
• Tiles have two sides One side with multiple
  colors and the other is red for negative.

How they work

• Algebra tiles work by the concept that every tile
  has a length, width, and area
• Algebra tiles provide a useful way to introduce
  operations on polynomials
• Algebra tiles can help students visualize
  equivalent algebraic expressions and/or equations
