Algebra (Class 81)
Announcements
Next Test-- date TBA (the calendar has really thrown us off our regular testing schedule).
Lesson Title
Quadratic Functions- Tracking a Ball
Overview
Our Warm-Up today, Lots of Lots 2, continues in the theme of the last warm-up. Students need to use their skills to measure and reason about areas and perimeters to solve a puzzle.
In our new set of lessons we will look at some other examples of where quadratic patterns of change arrive and improve our skill of using equations to make predictions.

Key Attitudes
Math is about investigating and confirming
Key Ideas
Quadratic patterns of change arise from many different situations.
A table can be used to determine if a pattern of change is or is not quadratic.
All quadratic patterns of change have a second difference that is constant
Key Skills
I can recognize and continue a pattern.
I can make a table of values to represent a pattern
I can use a table of values as a tool for describing a pattern.
I can use a table of values to predict values not in the table.
I can recognize a quadratic pattern of change and write a quadratic equation to represent this pattern.
I can measure with a ruler in cm.
I can compute area and perimeter of rectangles.
