# Transformations of Quadratic Functions in Standard and Vertex Form

#### 1 Independent Practice

http://www.yummymath.com/2014/july-4th-and-fireworks-on-your-calculator/

Using a graphing calculator, students will create 3 parabolas of various heights and widths by altering the a, b and c values of the equations and 3 parabolas by altering the h and k values. The students will follow the questions that correspond with the activity to help them think of the best equations to use.

#### 2 Direct Instruction

I will go to the website: http://www.softschools.com/math/algebra/quadratic_functions/quadratic_fu...

This website has an interactive manipulative that allows you to change the different parts of the equation. Students will be able to draw conclusions as to how a graph is affected by changing a certain number in the equation.

#### 3 Guided Practice

I will put a picture of a graph on the board and in groups, students will determine the best equation for this graph using their knowledge of direction of opening, width, y-intercept, and vertex.

#### 4 Wrap Up

Students will perform a gallery walk. Students will display their graphs and equations on their desks while their classmates walk around to see how similar and different these are from their own.
