45-45-90 Triangles

To learn the pattern of the side lengths of a 45-45-90 triangle, students complete a gallery walk, a card sort activity starting with using the Pythagorean theorem, and activity to locate if there is an error in a presented problem and if so to identify what the error is.

4.05 Histograms and Comparing Distributions

In this video, we construct histograms and use them to compare data distributions.

###
4.06 Box Plots and Comparing Distributions

In this video, we construct box plots and use them to compare data distributions. We also compare box plots and histograms.

11.02 Correlation

In this video, students will interpret the correlation coefficient.

###
11.03 Determining the Line of Best Fit

In this video, students will determine the line of best fit using least-squares regression.

###
11.04 Making Predictions

In this video, students will use the line of best fit to make predictions for a value of *y* given a value of *x*.
