Here are some educational websites I want to share with you.  I hope you find these to be as good a resource for you and your children as they are to me and my children.

 This website is a great guide for teaching reading and writing.  I've been printing out reading comprehension and grammar worksheets from this site, but there is so much more to explore.

 This is fantastic--a fourth grade teacher's entire curriculum with a lot of extras.  I feel guilty listing this, but it is so well done, I can't help but admire her site...and share it.

 This is really cute- a make your own story website.  There are other good story making websites but this is the one I introduced my girls to.  

 I really love this website, it's so well designed and fun for toddlers and early readers.  It's my own personal favorite.  Be sure to check out the "more starfall" and other "more" tabs on the website for additional learning material.  My girls still enjoy this site.

This website has many K-5 math, reading, writing and science worksheets.  

Math Star Newsletter was recommended to me by my patient.  I'm glad the answers are included.
Greg Tang Math was recommended to us by one of my daughter's teachers.  The website has fun, creative math games and worksheets.  There are many pages to explore so click away at the different icons on top and you'll be pleasantly surprised with all that it has to offer.  Our last names are similar but I have no affiliation with this website or the people involved with the website.  I just like it as a parent.

IXL.com has online exercises for math, language arts, science and social studies.  There are free and paid contents to explore.

These websites are great for generating your own math worksheets. Inside Mathematics is a site for educators. Please check out their problem of the month.

For general learning, Khan Academy and National Geographic Kids are great.  Khan Academy is my favorite website for older children.  I can't think enough good thoughts about it.  National Geographic is just great.  Kids love animals.  Enchanted Learning has all sorts of great worksheets about animals, maps, weather, languages, the rainforest and much more.  Kids.gov is the US government's official web portal for kids, which includes articles, activities, games and videos on a broad range of subjects, from the academic (government, math, reading, writing, science, history, social studies) to the cultural (art, music) to the practical (exercise, health and safety, online safety, money).

The Everyday Math website explains the new math program being taught in our public schools.  I thought the algorithms/computation videos really show how different our children's programs are from the programs I had growing up.  Our children's lesson plans and associated homework are all on the website.

Have fun and explore away!
