Laura Candler is an educator who has provided a website to help other educators better prepare. She offers many different subjects in her "file cabinet" and offers free printable worksheets. She also has classroom strategies such as classroom management strategies to help better maintain your students and classroom.
For elementary education this website would be perfect! It involves math games, and hands on math activities. They make all activities printable to be able to be used in math centers and in the classroom. Everything can be accessed using Adobe.
This website I found to be very helpful when it comes to language arts and spelling lessons in the classroom. It gives you many interesting ways to plan your lesson around spelling and language arts and general and gives many articles and useful words lists!
Scholastic really does have the whole package on their website. They offer so many different links from recourses and tools to books and authors. It is a great way to get ideas to keep your students focused and a great learning place for teachers to grow.
PBS has a website for everyone and makes it easy for everyone to use. There are amazing ideas for teachers to use in their classroom to better prepare them for their lesson plans, etc. PBS also offers websites for kids to play educational games and even a website for parents.
