Decimal Tiles

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!

Fractions Game for Math for Elementary Teachers

This is a game that I made specifically to show to my Math for Elementary Teachers class (I have been making a lot of stuff for the students in that class this semester which is why this blog has been sitting dormant).  However, I must say that I am very excited about this game that I just had to share it.  Long story short, it has been over 80 degrees in my classroom the last week or so, and going outside to demo this game with my students is the perfect excuse to get out of the classroom!  If you are teaching Math for Elementary Teachers, you are welcome.  The only thing I am not sure about is how the People Cards will look once they are printed, but since I have already set them to Gray Scale, my guess is that they will not look too terribly bad.
