What are Algebra Tiles?
  • They that can be pieced together like a puzzle
  • They are used to represent variables and
    constants
  • Product names may vary
  • AlgeBlocks, Number tiles, Dienes base-ten blocks
  • Can also make algebra tiles
  • Construction paper

3
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.

4
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

Addition, Subtraction, Multiplication, and
Division
  • Addition and Subtraction
  • Performed by adding or taking away tiles
  • (x2 2x 1) (x2 x 4)

7
Addition, Subtraction, Multiplication, and
Division
  • Multiplication and Division
  • (x 2) (x 1) x2 - x - 2

8
Factoring
  • Factoring
  • Take the completed product and figure out what
    would make that array.

9
Completing the Square
  • x2 8x 9
  • x2 8x 16 9 16
  • (x 4)2 25
  • x 4 5
  • x 1
