Back to School Motivational Quotation "Strength doesn't come from what you CAN do...it comes from OVERCOMING the things you once though you COULDN'T do." created by Tricks and Treats for Teaching Math. I print and laminate this poster and put it up in the classroom, and also inside the boys/girls bathroom. It's just a powerful, positive thought for students to ponder. Thank you for your purchase.
