Per a few requests, I have added temperature lows as well as the temperature highs.
Type in the daily temperature on your computer with your students and it will automatically graph it for you as you type. You can pre-print the monthly graph for everyone in your class and they can follow along and graph with you. I use it with calendar math or other daily activities.
Great for explaining the scales of a graph and practicing accuracy in graphing and using rulers to connect lines. Look for trends in weather and allow students to easily see the big changes from day to day. Try to graph the highs using the same color and the lows as a different color. (perhaps blue and red as this is what is seen on many weather channels for warm and cold fronts)
