Product Description
Algebra 1 Analyzing Lines of Fit in a PowerPoint Presentation

This slideshow lesson is very animated with a flow-through technique. I developed the lesson for my Algebra 1 class, but it can also be used for upper level class reviews. This lesson teaches how to use residuals to determine whether models are a good fit, find lines of best fit using technology, and identify correlations and causations.

The presentation has 40 slides with LOTS of whiteboard practice. Use as many or as few of the problems to help your students learn each concept. For more PowerPoint lessons & materials visit Preston PowerPoints.

Students often get lost in multi-step math problems. This PowerPoint lesson is unique because it uses a flow-through technique, guided animation, that helps to eliminate confusion and guides the student through the problem. The lesson highlights each step of the problem as the teacher is discussing it, and then animates it to the next step within the lesson. Every step of every problem is shown, even the minor or seemingly insignificant steps. A helpful color-coding technique engages the students and guides them through the problem (Green is for the answer, red for wrong or canceled numbers, & blue, purple & sometimes orange for focusing the next step or separating things.) Twice as many examples are provided, compared to a standard textbook. All lessons have a real-world example to aid the students in visualizing a practical application of the concept.

This lesson applies to the Common Core Standard:
High School: Statistics & Probability » Interpreting Categorical & Quantitative Data S.ID.6b, S.ID.7, S.ID.8, S.ID.9
Summarize, represent, and interpret data on two categorical and quantitative variables
6.Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.
b. Informally assess the fit of a function by plotting and analyzing residuals.

Interpret linear models
7. Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.

8. Compute (using technology) and interpret the correlation coefficient of a linear fit.

9. Distinguish between correlation and causation.

Please note that these PowerPoints are NOT EDITABLE. They WILL NOT work with Google Slides. You will need the PowerPoint software.

If you need an alternative version because your country uses different measurements, units, slight wording adjustment for language differences, or a slide reordering just ask.
