Reflection: Joy Tech Time - Section 2: Put It Into Action


I was hoping that setting this activity up to be a competition would spark more interest than simply giving the same problems as a worksheet and it succeeded, but not as well as I'd hoped.  I think my small group doesn't get as competitive as a larger class might because they anticipate who will win.  They stayed engaged throughout the lesson, but I think if I have an equally small class next year I'll try something a bit different.  I may try changing the pacing by giving a set time to give a response or give 3 points to the first correct answer, two to the second, etc, and taking points away for incorrect answers.  While this still keeps it competitive, it mixes it up a bit, so that teams that work fast but don't check their work end up losing points.

Unit 7: Building Functions
Lesson 5 of 12

Objective: SWBAT evaluate the effect on a graph of replacing f(x), by f(x)+k, k f(x), f(kx), and f(x+k) for specific values of k using technology. SWBAT explain the effects described above using technology.

Big Idea: Use graphing calculators as tools to evaluate and explain, yes, explain!, changes to a graph.
