Do you remember Scholastic Book Fairs at school when you were a kid? I looked forward to browsing through the books and picking my favorites. When my boys were little we went to their big warehouse sales in Anaheim and found loads of treasures.
Today when I was searching for ideas about how to experiment with topology, I came across Scholastic Printables! You can pay them by the month or by the year and print all you like. They have very nice printable pages to give your kids all kinds of ideas and inspiration in all subjects.
In fact, I’m pretty sure you could create enough lesson plans to cover most of the required subjects for the entire year from their Teacher Resource page!
