1. Connect Four Using Technology to Enhance Classroom Instruction

2. Connect 4 Great emphasis is placed on the four representations of a function. Connecting the verbal, numerical, graphical and algebraic forms of a function can be facilitated by using graphing utilities.

3. The height in feet of a ball thrown upward from the top of a building after t seconds is given by h(t) = – 16 t 2 + 32 t + 128, t ≥ 0 NumericalGraphical

4. Connect Four The three different forms for a quadratic expression are: Standard form: – 16 t 2 + 32 t + 128 Factored form: – 16 (t – 4) (t + 2) Vertex form: –16 (t – 1) 2 + 144

5. Which form is most useful for finding the smallest/largest value of the expression? The three different forms for a quadratic expression are: Standard form: – 16 t 2 + 32 t + 128 Factored form: – 16 (t – 4) (t + 2) Vertex form: –16 (t – 1) 2 + 144

6. Which form is most useful for finding the values of t when the expression is 0? The three different forms for a quadratic expression are: Standard form: – 16 t 2 + 32 t + 128 Factored form: – 16 (t – 4) (t + 2) Vertex form: –16 (t – 1) 2 + 144

7. Which form is most useful for finding the value of the expression when t = 0? The three different forms for a quadratic expression are: Standard form: – 16 t 2 + 32 t + 128 Factored form: – 16 (t – 4) (t + 2) Vertex form: –16 (t – 1) 2 + 144

8. Connect Four Graphing utilities can be used to help make connections among and between different representations of a function Graphing utilities can be used to develop mathematical concepts. Graphing utilities are not magic black boxes, they are tools that should be used to facilitate learning.
