With FREE membership, Spigot Science Magazine offers online issues full of science with math, language arts, and social studies add-ons. Each issue includes games that can be printed, and there is also a teacher’s guide to go with each issue. You are also not “stuck” with just the subject of the month – you can view back issues and use them to complement your current studies. Science can sometimes be difficult for me to teach, but I love to find resources like this one!
