Residual Plots II
This app helps illustrate how the residual plot relates to the proper choice of a function to fit a particular data set. Students should learn to look for a random, scattered pattern to the location of the residuals, rather than a predictable curve shape. (S-ID 6a)

Proof by Shear Transformation
This app allows you to explore geometric proof that is a variation of the original Euclid’s proof. In this proof, the shear transformation is used to change the shapes without changing their areas.
