PowerPoint lessons are helpful in teaching math because the slides can include important formulas or guidelines for students that can remain on an overhead projector for reference during classroom lessons, activities and tests. PowerPoint is also useful for displaying sample test questions and multiplication tables.
The use of PowerPoint to teach math helps incorporate technology into the classroom, which helps students learn math in practical ways. Instructors can host games while displaying questions for teams to complete on a PowerPoint slide. The program allows teachers to quickly and easily move to the next slide when reviewing math equations, sample questions or game rules.
