In case you are curious, every short vowel pack has pretty much the same materials, which is nice for consistency. You can mix and match or teach separately. I use these hands-on colorful materials with my Printable Phonics Packs. I like to have both options. 🙂 The kids I work with need plenty of opportunities to practice sounding out these words in isolation and in context. I included varying levels of difficulty so you could start with the very beginning readers and move up to kids with experience sounding out words.
