This flipchart is used for the Everyday Math Third Grade curriculum. It helps the students learn about how the length of daylight changes throughout the year, Daylight Savings Time (if you live in a time zone affected by it), graphing, and elapsed time. My students love getting to work on their graph once a week to document if our days are getting longer or shorter. I have added extra pages at the back of the flipchart so that you can move them when you have filled up the first page of each chart/graph. Enjoy!
