The Alex website is a teacher website built with the necessary tools for a teachers convience. It has lesson plans on it that you can choose from any subject or grade level. Different teachers put their lesson plans on their to share with others. It also has a Library media source so that teachers can help students help find the right media for them. It has grant opportunities if a teacher wants to do a project dealing with education then they can get more information. If you don't know the exact lesson plan then you can search the topics and it should come up with a lesson plan or general question about the website. It also has ACCESS where you can set up for your students to get a particular subject from another school on a computer with ACCESS capability.
I like the website because if you dont know what to do for your day at school then you have plenty of ideas at the touch of a button. It has detail to details about math lessons. It has one activity but the different ways you could teach it to the various grade levels. I also like that is a free website.
