My goal for this mini unit was to give the students an understanding of the difference in linear and non-linear relationships and then revisit these ideas throughout the year.

__Functions and Relations__I introduced the students to the basics of functions and relations and how to tell if the relationship represented a function and whether a relationship was a linear or non-linear function.

Examples of "Collaborative Team" practice problems.

After practicing and discussing collaboratively, students transitioned to iMath and worked on my self-paced Socrative lesson on

*Identifying Linear and Non-linear Functions.*

Here is my Socrative Code for this lesson:

Identifying Linear and Nonlinear Functions - SOC-18219609

Check out my Free Resources Socrative Page to see all of my Socrative Codes.

__Non-linear Functions__I introduced the students to non-linear functions in real world situations using the "Zombie Apocalypse".

__Graphing Stories__I introduced the students to Piecewise Functions and understanding the parts of a graph and the intervals.

I modeled the first Graphing Story for the students, showing them how to focus on the changes and the time that was shown and how to mark those intervals with points on the graph.

I had the students do the Graphing Stories as Collaborative Teams. For each video teams rotated Recorder/Reporter, using one team graphing mat. Students watched the videos a few times and as a team determined the intervals and points. The students then compared their team graphs with the graph's solution.

__Interpreting and Drawing Graphing Stories__I introduced the students to Interpreting and Drawing Graphing Stories from situations.

__Reflection:__It really did help starting the concept of functions in my Linear Relationships unit. But this unit really needs more time. I am hoping that next year's schedule will allow for at least another week for this unit. :o)

Thanks for stopping by and checking out my blog.... :o)
