Exploring Different Representations
Quadratic Tiling Patterns
• Open envelope A • Distribute the contents equally
Step 1:• Which representations belong together?• How do you know?
Quadratic Tiling Patterns
Step 2: Examine the various representations.
What information does each representation tell you about the quadratic function it represents?
Step 3:Match the algebraic and pictorial representations.
I spy a representation that:
1. Shows me that quadratics do not form a straight line.2. Shows me the factored form.3. Shows me the “completed square”.4. Helps me see that x is a variable.5. Helps me see that a polynomial is a sum of functions.6. Shows me that the first differences of a quadratic are
constant.7. Shows me that the second differences of a quadratic
are linear.
