The temperature graph is to be filled in everyday. You will need to print two and glue together to make the graph long enough to last a month. The rectangular box on the top left corner is there for writing the month (I start writing the abbreviation for each month about half way through the year). Everyday, the kids read your outdoor thermometer and then record the temperature on the graph. At the end of the month discuss the weather and then erase and start over. You can also graph the days as being hot, warm, and cold.
