This sight is awesome for making customizable content for math pdf files. I used the pdf files as time tests, supplemental math, as pdf files on the interactive white board, and as home work. It makes it completely easy to differentiate for different learners.

I love the sight for good activities and printables that work well with elementary students. There are good vacation journals and book logs that I have used. Every time I look, there is something new that I didn't see before.
