Oh boy! I have a wonderful curriculum to recommend:
Konos Unit Studies
You'll want to read this little gem from Jessica Hulcey, the creator of Konos Unit Studies.

If you click on Tea Time with Jessica, and Archives, you'll find another excellent article : How We Teach Changes Brain Size.

Add Math U See- a kinesthetic math program, and you'll be all set!
