Reflection: High Expectations A Gallery of Cubic Functions, Day 1 of 2 - Section 2: Making Sense of the Problems

 

It's at this point that I will get the comment, "Wow,  I feel like I'm in kindergarten again."  Usually it's said with a bit of disdain, and the student really means something like, "Is this your opinion of me?  Do you think I'll like math class because we get to cut and paste?"

I'll handle this lightheartedly, but it's true that high school students want to be taken seriously and want to be treated like adults.  They're quick to sense condescension, even when it isn't intended.  I'll respond that while I wouldn't ask them to "cut and paste" if it weren't for a good reason, most of them will admit there's something satisfying about it.  In this case, the reason for the cutting is that it's important for the students to be able to see the graph next to the equation so that they can quickly use the one to understand the other.  So, let's have fun while we can!

While they're busy cutting out the graphs, there's generally a lot of joking around, which is great.  I only ask that they work quickly and safely!

A Gallery of Cubic Functions, Day 1 of 2

Unit 3: Cubic Functions
Lesson 5 of 13

Objective: SWBAT match graphs to equations for a variety of cubic functions. SWBAT convert a cubic equation from expanded form to factored form when roots are given.

Big Idea: The equation helps us identify the graph, and the graph helps us factor the equation!
