This 2 minute video will help students remember the direction of positive, negative, zero, and undefined slope. This video is great for English learners and students with learning disabilities because there are minimal words on the screen for them to read. The animation will explain it to them. The music and the images will keep them engaged.
The image at the end of the video is the key in helping students remember the different types of slopes. I have my students draw the "slope tree" on their notes and homework and has been very successful.
