Algebra (Class 84)
Announcements
Next Test-- date TBA (the calendar has really thrown us off our regular testing schedule).
Lesson Title
Putting It All Together
Overview
The warm-up for today is the last in the series “Lots of Lots” before the one that will be on the final. There are a few extra copies of past ones in the folder and re-doing some of them would be a good idea!
The lesson for today brings together many of the different representations of quadratic functions: equations, tables, and graphs. Students need to be fluent in moving from one of these representations to another.

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
Quadratic functions can be represented by equations, tables, graphs, or words.
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.
I can understand and use an equation, a table of values, a graph, or words to describe and make predictions about quadratic functions.
