Odd and Even Graph

Each day, a student adds one mitten to the graph and records how many mittens are on the graph. When there is a mitten without a partner, there is an odd number of mittens. When all the mittens have partners, there is an even number of mittens. You will need to clear the data from the graph to start with a clean slate. This activity is based on an activity found in the calendar math program called Every Day Counts!
