PRODUCT DESCRIPTION

24 Pages. This unit on scatterplots and trend lines is designed to accompany the study of linear functions. It is fully aligned with the Common Core Standards. Students should already be familiar with the following:

* Writing equations of lines given slope and y-intercept or point and slope
* Graphing points and lines (from slope & intercept and from point & slope)
* Identifying slope (rate of change) and intercepts from a graph

I have used this unit in both a beginning algebra course (between linear functions and systems of linear equations) and an advanced algebra course (in the introductory unit on linear functions). It consists of three parts:

1. Introduction to scatter plots and trend lines through an analysis of Olympic swimming results. Students first learn to work with scatter plots by hand plotting and drawing trend lines. Equations are used to explore and interpret the scenario.
2. Student Activity exploring an epidemic of West Nile Virus. This lesson introduces technology for calculating regression equations and explores non-linear regressions. Instructions are included for TI-83/84 and MS Excel (more possibilities available, upon request).
3. Performance Task Assessment: two fictional families travel the frontier in search of the American dream. Students must use their regression skills to analyze data taken from found journals in order to determine if either family makes it before running out of water. Comprehensive grading rubric is included.

This unit contains full answer keys for all handouts as well as a cover page detailing essential question, common core standards and student objectives, and teaching notes.

I am a new seller. Your feedback is my foundation to a good start. A full version of the unit (less answer keys) is available for free preview on the right. Feel free to take a free look before you purchase.

Thanks for stopping by!

I purchased this back in August & am using it next week for American Education Week. This is an amazing resource for teaching scatter plots & linear regression. I love the creativity and real world applications. I did note one tiny typo, could you possibly fix the charts on pages 11 & 12 to say "21" days and not "2" days? Thank you so much for this valuable resource. Can't wait for my kiddos to work on it next week!

BTW, I don't see how anyone can not give this product a 4.0 rating for thoroughness & creativity. A+ in my book!
On  November 21, 2012The Allman Files answered:
Thank you Laura for your critical eye. I fixed the tables on pages 11-12 and even found a couple of other minor typos.

Your compliments made my week!

I purchased this unit and I think it is wonderful. I am wanting to use some of these activities for my IBL unit at my middle school. We have a closed internet portal that only my students, myself, and administrators have access to with usernames and passwords. Would I be allowed to put some of this material on this portal for my unit if I show where my resources came from. This portal can not be accessed by anyone on the internet except for my current students. The point of the portal is so administrators can see what we are teaching electronically and if a student is absent they can stay caught up by going on the portal and doing the activities on their own. Let me know if I have your permission. Thanks for the great material!
