The magic of homeschooling is sometimes knowing your strength and weaknesses so you can compensate. That said, we all have our gifts but art is not one of mine so I was very excited to try out Spears Art Studio. I got their K-8th art curriculum and it is designed to use with multiple ages at the same time. I love that because it is hard enough to do art but much less coming up with the time for 3 different lessons.
This program is a definite winner! I got the program completely on a CD ($39.95) and it lays out everything! It is set up on an academic year but you can pick and choose what lessons you do. It has a main lesson for everyone and then has broken out projects for each grade level. The program provides graphics to print off and a list of materials needed. It is really easy to follow with or without any natural talent.
Spears Art Studio also has a high school curriculum and a calligraphy program. I highly recommend this art curriculum for anyone but especially those with more than 1 age group.
