This lesson was designed for use in a Foundations of Algebra class. I use iSpring Suite. The software was not difficult to figure out, but did crash my computer a few times. I also was not able to find a quiz format that would allow learners to enter fractions. So any slopes that require fraction answers have to be entered as 1/3 but show as 13. The students in the class need to be answering with fractions at the time this lesson is designed for. I will ultimately need to have them take their quizzes in Instructure Canvas.
