Math Aids allows you to make custom math worksheets for the skills you are working on! I kind of love this site right now.
Learning Language Arts Through Literature has been one of my favorite curriculum since One was around the age Four is now. Wild. I just pulled down our second grade level book (the red book) and have been using it with Three for a couple months. I had forgotten how much I love it. I'm so happy I saved them (I have them through 6th grade.) The website allows you to print out a sample lesson to work through. And I will say that there is some Bible in there (we recently did a lesson about David and Goliath) and I know that can upset some very secular folks. Full disclosure and all that.
