One of the challenges we have faced this year is a need to homeschool on a very limited budget. This has required a tremendous amount of internet research in order to find good resources at low or no cost. Some of the jewels I am using this year include:
abcmouse.com to supplement kindergarten skills
sparknotes.com for their quizzes and essay question suggestions for classic literature (We have been doing a lot of Shakespeare for senior English.)
khanacademy.org - for my youngest daughter who has a great conceptual grasp of math concepts but becomes intimidated when she sees that material is two or three grade levels above her grade
I will save some of the others to discuss later. These are just a few of the tools that we are using this year. We are also planning to do NaNoWriMo again this year, which fits well with the creative writing course I am teaching. If you have kids that love to write or kids who think they couldn't possibly write enough to fill a book, check out the Young Writer's Program at nanowrimo.org.
