K-12 created a free Spelling Curriculum for grades K-12. The 36-week program consists of:
- weekly spelling lists
- printable worksheets
- dictation sentences
It is based on academic subjects typically taught at particular grade levels (such as science subjects), and it includes Fry's 1,000 most commonly used English words.
