Algebra (Class 83)
Announcements
Next Test-- date TBA (the calendar has really thrown us off our regular testing schedule).
Lesson Title
Measuring Jumps
Overview
The warm-up for today, Lots of Lots 4, continues to push students concepts of area and perimeter while building their reasoning skills. Our lesson for the day also continues with using tables, graphs, equations, and words to reason about quadratic functions. Specifically we analyze and compare the time and height of the jumps of a frog, a flea and a basketball player.

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.
