Reflection: Developing a Conceptual Understanding Estimate! - Section 3: Wrap It Up


Some of my students are still intimidated by graphs that aren't linear or quadratic so this lesson helps build their confidence about working with graphs of functions in general.  It was interesting to see which students actually used a slope formula to estimate a line between the points at (1, ?) and (2, ?) and which students just took a guess about what worked.  I even had one student who put equations in his calculator several times and used the table option to get points.  His Tips for a missing student show that he really does understand this lesson, as did the fact that he won the competition handily.

Unit 8: Interpreting Functions
Lesson 6 of 19

Objective: SWBAT estimate the rate of change of a function from a graph.

Big Idea: Just like estimating the number of jelly beans in a jar, your students estimate the rate of change for graphs with the best estimate winning the prize!
