This site is like Cliff’s Notes, only for younger audiences. By taking a look around, users will be able to find simple but truly useful resources to help kids in elementary thru high school achieve their very best in any and all subjects.
The site is very nicely designed, and also carries resources for teachers and parents, so it will be appealing to a large audience. If you are looking for worksheets, exercises and lesson plans, you will be able to find them here as well, and you can read them online for free without being asked to register or any other thing, with a big plus: the site always displays related searches, so if you are looking for material on the Civil War, you’ll also get links to articles dealing with the biography of Lincoln, the principles of the constitution and other social sciences topics. I was happy to see that the site not only provides subject information, but also methodological guidelines to help kids develop effective and lasting research and study abilities, even if they have learning difficulties.
