A friend told me about this yesterday and I was super excited to share. It looks very well put together and is FREE for a year. It is a complete curriculum for 2nd to 5th grade which is roughly equivalent to 7-8 to 10-11 years old. Go check it out!
Note: You have to give them your email address to get an account. Mine will be activated by the 2nd Oct and I cannot wait.
I was sent a link to a couple of lessons and the kids jumped straight in. Oh the fun they had. Look out for the photos.
