Free Online Math Resource

Summer is now in full swing! Are you looking for some fun, FREE, online educational games to help keep young minds sharp during the summer months? The fine folks over at Math Nook have a great selection of mathematics activities for your student to enjoy while they hone their math skills! I used several of these games last year while we were completing a unit on even and odd numbers. The students LOVED the games and it really improved how quickly they could recognize a number as even or odd. Do you know of any other similar resources?
