Time Magazine provides themes for teachers and students varying form grades K-6. This website includes worksheets, printable quizzes, and graphic organizers.
This website has so many resources for teachers, including lesson plans, activities, calender ideas, parent & afterschool resources, inspiring stories from other teachers around the world, and so much more! What I really like is that, although this large amount of info can be overwhelming, you can choose the grade you will be teaching and narrow it down to all of the resources for that age group :)
This teacher provides you with technology tips and resources that you will need in your classroom. She also provides powerpoint templates and ideas, as well as how to design your own classroom website!
This site I listed as being a SPED resource but it is also for all other students including bilingual. Unfortunately it isn't free but with a paid membership, it offers a great deal of materials such as classroom management, printables as well as a good subject range.
This is an interactive website that was created by a school teacher and is approved by school teachers around the world. The website is set up with the games grouped by grade level. The website also introduces basic computer skills and provides a tutorial for using ABCYa buttons. The graphics are awesome and some of the games have sound which adds interest to the games.
Activities for preK-12. A neat interactive learning website. Students can do character analysis for reading, build a dinosaur for science, math hunts for math.
This site has a Classroom Resources section (lesson plans, interactive activities for students, class activities, and printouts). The Professional Development section includes teacher resources and strategies to improve student literacy.
Great site for reading and writing activities. Includes story mapping, diagramming, and poetry. Lesson plans and teaching ideas are also available for teachers. Content applies to grades K-12.
This website is ran by discovery education. Administrators, teachers, parents and students can use this website. It has lesson plans for K-5 for pretty much any subject you are looking for.
