The Buoy is designed to be off-balance, like its namesake bobbing device, though not as extremely as a Pilates ball; the idea is that the microadjustments you're continually making with your body are not annoying enough to be a hassle, but adequate to burn some calories. Also unlike a Pilates ball, the Buoy is height-adjustable.
This time of year there’s no one more highly organized than a teacher. In addition to getting all those seating charts, lesson plans, and assignments in hand, an ultra-tidy classroom space makes all the rest of those tasks easier. So you can bet teachers keep their rooms and desks shipshape. Luckily, that means there’s lots of smart, crafty, even downright cheap ideas out there to crib from.
