Educators of all sorts are always looking for helpful resources. If this is the case for you as a parent or teacher, you will want to check out Education.com.
Education.com is most useful for homeschool parents and teachers of young children, particularly kindergarten through 5th grade.
They have resources for a variety of subjects: math, reading, writing, science, and social studies. And these resources include worksheets, online games, lesson plans, and online activities.
Be sure to check out other reading activities as well.
The subject matter is fairly basic, so it should not be an issue that Education.com is not explicitly religious. I hope you and your children enjoy their materials!
