Thank goodness there are countless online resources to help — for any grade, and for any subject or interest. Some websites include Khan Academy, a site with hundreds of videos and online tutorials for K-12 students across a variety of subjects; Bill Nye the Science Guy and Code.org, which focus on science and computer science respectively and offer both lessons and hands-on projects; or the BrainPOP or National Geographic Kids websites, which have educational lessons for all children. These and many other resources are readily accessible, largely free of charge and can often be downloaded for use offline.
