This product includes a PowerPoint and a student worksheet to do with the presentation.
The presentation begins with two vocabulary words: Adjacent and Interval. Then it teaches the students two short little songs to help them remember how to figure out the interval on two different number lines (one that has ADJACENT numbers, and one that does NOT have adjacent numbers).
The powerpoint is designed so that you and the students can figure out the answers, and then you click to show the correct answer on the screen. It's very interactive!
After the interactive teaching portion of the PowerPoint, there is a vocabulary review of the two vocab words, and then two practice number lines. The practice numbers lines are part of their student worksheet, but they could also be done on individual student whiteboards.
This makes teaching number lines a little more fun for both the teacher and the students!
