## Reflection: Joy Graphing Quadratic Functions in Vertex Form f(x)=a(x-h)^2 + k. - Section 2: Power Point

The Kinesthetic Activity in this lesson on slide eight really helped students to understand the horizontal and vertical shifts of a Quadratic Function in Vertex Form.  Students had fun stepping to the transformations, and following the two student volunteers.  It helped students to reinforce what they had learned in the lesson based on the structure of the equation (MP7).

Students were successful in the Exit Slip on explaining the horizontal and vertical shift.  I believe it was this activity that helped them to synthesize the information provided earlier in the lesson and be able to explain the differences in the transformations.  This Kinesthetic Activity was a good way to differentiate the lesson for all learners.  It helped some to gain knowledge they did not learn within the lesson, and summarize the transformations for others.

Some of the students still struggled in the Exit Slip when a is not equal to one.  We discussed at a later time that when a is greater than it will create a greater y value.  Plotting a greater y-value stretches the function, and therefore makes it more narrow.  Multiplying the function by a value of a that is less than one, produces a smaller y-value.  Therefore vertically shrinking the parabola, and making it wider.
