Yeshivat Frisch juniors in Shira Teichman’s Algebra II class recently learned about piecewise functions. Teichman wanted to do something a little more out-of-the-box in honor of Yom Ha’atzmaut, so decided to challenge the students with a unique activity: draw the Israeli flag on a coordinate plane using their knowledge of piecewise functions. The day after Yom Ha’atzmaut, she had the students log on to desmos.com and showed them how to limit the interval of a graph on the computer program. Then, she simply gave them the go-ahead to start graphing. The active-learning assignment integrated math, art, technology and the Jewish calendar, and was open-ended since there is no one correct way to draw the Star of David within the program!
