This is a packet with increasing difficulty, in words/sentences, for all short vowels sounds (a, e, i, o, u). It works as a great classroom strategy for students who need extra support. Best if used with the dot stampers (I used the sparkly ones as incentive) as a reward once a page is completed/passed with no errors to document progress. Simple, yet effective, classroom intervention! A GREAT resource for documentation (504's, IEP's, referrals, growth, etc.)!
