I use these Short Vowel Cards in my Daily 5 Word Work Centeres and during Orton Gillingham Phonics Direct Instruction. The words come phonics instruction. Most of the words on these cards came from the manual. Although I have been teaching for 11 years, I have only used the Orton Gillingham program for 7 years. You could easily use these cards as part of any phonics instruction program. I have 5 sets of short vowel word cards listed.
