I tried to do more computerized stuff for grading and was trying out some Switched on Schoolhouse. I ditched it all except math. My kids would just sit and click answers until they got the right one and would continue. They can't do that with math ;) so that will work ok - especially the fact it grades the questions and honestly I was tired of grading math for daily work all the time.
Purchased the Business Math book from Simply Char. Mason and LOVE IT!! Got the eBook format so I can print it out for both kids and I really think it will help my son see what it takes to run a "business" (even though he does it with his 4-H animals he still doesn't get the real value of money yet)
I'm still debating on vocabulary and spelling - but I think I might just work with some lists I have for spelling - at least for my daughter. She's taking sign language locally and she needs to spell the words for next years class. However, I'm still looking (I think that's 1/2 the fun)
Most of the rest are all book for our Ambleside Online year (year 3 & 5) and I threw in GrammarLand for both kids.
