Rosetta Stone Spanish: The easiest way to learn a language... for the student AND for Mom! Believe the commercials.
Truthquest History: The ultimate living history book list! If you enjoy learning history through literature, this is an incredible resource. Michelle Miller's commentaries through the guides are extremely helpful.
Teaching Textbooks: Everyone I know who is using this curriculum for math is ecstatic. The teaching DVDs are easy to navigate and lessons are taught very well. My kids rarely need any additional help. And they love the graded lessons and quizzes and the grade book feature.
A Reason for Handwriting: This is great for practicing handwriting for any elementary grade (beginners through cursive). Where other handwriting books may give sample sentences to practice, A Reason gives scripture verses as the copy.
Institute for Excellence in Writing: This is a big hit with many homeschool families I know. This is our first year to use it, so I'm still in the learning process. I am very excited about it! I've tried teaching writing on my own without any curriculum at all because English is my favorite subject, and it's time to call in some reinforcements. Gotta love the DVD teacher when things get tricky!
