Even and Odd Numbers

We began learning about even and odd numbers by reading the delightful book, Even Steven and Odd Todd.  Then, we discovered a "handy" trick for determining if a number is even or odd.  We take the digit in the ones place of the number and build it with our fingers.  We then match up our fingers to see if each one has a partner or not.  If all fingers have a partner, the number is even.  If not, it is odd!  We went on to do some activities and play games to practice this skill.
