Every teach requires materials to run their classroom and it is not always easy to acquire them. Finding them online is one way to go about at least getting an idea of what could be done. We will all need to build up our own curriculum and supply the materials to our students that they need to succeed. This includes if we end up in a classroom where we are not entirely certain of what to teach.
There are times where we will be unsure of what course to take within our classroom. It helps to have others around that may have attempted it before you and can give you some measure of guidance. This can be done through networking not only within our own schools, but also reaching out online to other teachers around the world. We will not always have the best ideas, and multiple minds are more apt to find a solution than one.
