This is a great resource for chemistry teachers. In particular, I recommend the math skills area and the "Introduction to Stoichiometry" (Level 3, especially!).
This is a great overview web site for those teaching science (specifically chemistry). We will be using ChemCollective and PhET simulations this fall and are still reviewing others

Using this software, students can virtually participate in chemistry labs that correspond to the lesson taught, for a risk-free and safe environment for all ages.
This is a free online whiteboard where students can collaborate on chemistry and math problems without worrying about typing symbols. Also students can work on group projects together.
