How I Use It
I used this to introduce the angles associated with parallel lines. Drawing parallel lines and measuring the angles was a snap after learning how to get the angles measured by the three points to make the angle and only in a counterclockwise fashion. Once I went through a number of the tutorials and read parts of the manual, the product was easy to use and to have the students work with
My Take
I like the interactivity of the diagrams where the kids can manipulate the drawings so they can explore what happens to the angles when they move the lines around. I think the tutorials should be the first thing they give you the first time you sign up. I see great potential with the interactive worksheets for the students to use later on in the course. I really like the ability to enter LaTeX for formulas that are beyond a strictly text inputs
