This is a Microsoft PowerPoint presentation on a subject I call “The Incredible Invisibles”. It covers a concept in math that is initially confusing to students. There are a number of “Invisible 1’s” in math that are not shown as they are considered “normal math convention” or “default values”. These invisibles apply primarily to coefficients, exponents and denominators. I have also found in my teaching that there is also an “Invisible 2” that is confusing to students as well. This presentation introduces and addresses these invisible values to hopefully make their use clearer to students. This is a fully animated slide presentation in which the teacher or presenter can modify the extent of the animation as desired. I have taught 7th, 8th and 9th grade math and have used this ppt slide pack as an initial instructional resource (and refresher at times) for all three grade levels.
