GREAT IDEA: The Wall of Remediation. Each folder contains multiple copies of a worksheet students use to practice a particular skill. Early finishers select a worksheet for the skill they need to practice. Click through and read the blog. He's great!

Remediation Wall - great idea. I teach 6th, 7th and 8th grade math. I think I will use this idea for those pesky little skills like dividing fractions, rounding decimals, adding and subtracting integers, etc. Having a binder nearby with answer keys really makes this user-friendly!
