I spent the day printing math sheets for Gr. 1. Let's see where she is. I, of course, think she'll fly through grade 1, she knows this stuff, but then again, I thought she knew the stuff in the Gr. 3 books.
2 of my favorite free sites are:
homeschoolmath.net - it's a refresh site, where you can click on the topic you like and just hit refresh every time you print something and it'll be a whole new worksheet
tlsbooks.com - not a refresh site but it had LOADS of printables. This site is also multi-subject and grade.
Now I need more ink lol
