Per a few requests, I have added the capability to graph the low temperatures as well as the high temperatures.
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 do the high with a different color than the low. (perhaps blue and red as seen on many weather channels)
Buy it for yourself or share freely with your grade level team
