High School teachers often find that when they hear about resources, they are created for younger students. For this reason, I want to start out telling you about SAS Curriculum Pathways.
This is a site with high-quality, ad-free, interactive activities based on standard high school curricula in the areas of English, Science, Math, Social Studies, and Spanish.
When you go to the site, a tech person at your school will need to register for a subscription. They will then receive a generic login and password for teachers, and another for students (username only.) The first time a teacher logs in with the generic information s/he will be prompted to create their own unique login information. Students will always use the same generic username, since they are not saving any information to the site's servers.
Please take a look at this site! I just know you will find some useful activities there for your students to do at home, to use for teaching, and for students to do in class.
