Reflection: Checks for Understanding Change! - Section 1: Set the Stage


It was a pleasant surprise to find that the majority of my students had a good understanding of rate of change!  Their discussions about the possible rates of change for the given function made it clear that they understood that the rate was not constant.  In fact, when the solutions were posted only one student remained confused about why there was not a definite "slope".  A classmate asked to explain at the board, so I stepped back and watched as he sketched a  quadratic and proceeded to use a ruler to show that the slope was changing all along the curve.  It was great to see the confused student nod, ask a few more questions, and then say "I get it now." with conviction.  If all my lessons started this well we'd never have to backtrack or take extra time to review and revisit - what a treat!

Unit 8: Interpreting Functions
Lesson 5 of 19

Objective: SWBAT calculate the average rate of change of a function over a specified interval. SWBAT interpret the average rate of change of a function over a specified interval.

Big Idea: Just what does that change mean? Your students build understanding of rate of change as they calculate then interpret their work for each other.
