Every semester I always say that I want to do more to help my Pre-Algebra students understand the idea of ordering decimals from least to greatest. The Decimal Tiles below are part of my attempt to do so. To prepare this activity, I pre-cut about 10 sets of the tiles and had my students work in groups of 2-3 to order the tiles from least to greatest. Although all of the groups did not get the order correct, they were on the right track and on average had just a few numbers out of place. What impressed me the most is that the students were talking about which numbers were smaller than the other numbers and why. I overheard one student explaining to another student that negative and positive numbers are on a ‘continuum’. I believe that the discussion that occurred among the students was invaluable. If you come up with any other uses for these Decimal Tiles, I would love to hear about them!
Believe it or not, I was searching for Prezi’s about Fractions, and I found one here: http://www.diigo.com/list/aadavis/prezi-examples. You should definitely head on over there and check out all of them!
A few months ago I had students in my Basic College Math class create a game about fractions. One student created “Fraction Bingo”. I decided to search the web to see if there were printable bingo sheets available. Well, there were, along with some other activities that I found on the same website from Holt, Rinehart, and Winston. And below is a list of a few of my favorite ones, appropriate for college-level basic math classes (organized by topic):
