"Fractris" Teacher Support


Fractris Archived PoW || Student Version

Fractris is no longer the current ESCOT Problem of the Week. The student version allows teachers to use the problem with their students without giving the students access to the archived answers. Teachers can use the link to the archived problem to get ideas of student thinking.

Fractris asks students to use different combinations of fractions that sum to 1 in a Tetris-like game setting.

This ESCOT PoW could be used as a way to build students' fraction fluency, and also as an introductory exploration into adding fractions and finding common denominators.

If you have something to share with us as you use any of the links or suggestions on this page (something you tried and changed or a new idea), we would love to hear from you. Please email us.
