Algebra (Class 82)
Announcements
Next Test-- date TBA (the calendar has really thrown us off our regular testing schedule).
Lesson Title
Measuring Jumps
Overview
Lots of Lots 3 is our warm-up today, continuing the theme of solving a logic puzzle which requires measuring and calculating area and perimeter. Our lesson for the day also continues with the theme from last class-- 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. Students also begin their review for the final exam by creating examples for the topics which the exam will address.

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.
