Awesome website! This site extremely vast in educational topics and links for assistance. The teacher tool kit link is priceless. You are able to generate worksheets, create word bingo activities (great for vocabulary retention) and there are lesson plans (i.e. sentence starters). My favorite link is the alternative assessment; here, you can find ideas and rubrics for alternative assessments in your classroom.
This is an awesome website with short (and free!) videos to help teach all types of math from 1st - college and some higher level sciences. It's great for those days when the kids don't want to listen to your voice anymore.
