This PowerPoint file (47 slides) includes place value of both whole numbers and decimals with some work turning decimals to fractions and mixed numbers and vice versa. There are multiple problems on each of the PowerPoint slides. Each problem appears with directions on a "click" and then when you "click" next, the answer will pop up. "Click" again and another problem appears. A lot of "clicks" are even animated with sound. I use several of these slides each week throughout the year to review in addition to almost everyday when I focus on place value for my current area of study. I hope you will value the time put into making this file. I have changed and edited throughout the years to mainly focus on test prep type questions.
