Classroom timers.. all sorts! Teach time and number and the Olympics using various time keeping methods! See our pins about Olympic teaching/teacher resources pinned by Clever Classroom - http://pinterest.com/cleverclassroom/olympics-2012/
What a great idea for conferences~! This teacher makes a board of some handouts perfect for practicing at home, because so many times the parents want to help but aren't sure how (or don't have the materials). Brilliant!
