I have found a PDF file with the 1200 most frequently used words in writing.

The words in this list are in the order of their frequency of use in everyday writing.
Since the is the most frequently used word in the English language, its number one.
The first 25 words are used in 33% of everyday writing.
The first 100 words appear in 50% of adult and student writing.
The first 1,000 words are used in 89% of everyday writing.
Here’s the site where I found the list.
There is a book called Sitton Spelling Source Book Series which will organized the words so that they can be incorporated into learning and review each year through eighth grade.
Here are some examples that contain the grade, word list and internet games:
First Grade
Second Grade
Third Grade
Fourth Grade
Fifth Grade
Sixth Grade
Here is a Cybrary Man’s Educational Websites to sort through and find the best free spelling links to internet games, quizzes and PDF files.
Here’s a list of 40 ways a student can study their spelling words.
This really draws out my blog but here’s the entire list of 1200 words:
