Included in this set are signs for each vowel sound and a resource page you can use for examples of each letter combination for all of the sounds. These signs can be hung in your room as a reference for your students that they can use when they are reading or writing. They are a good supplement for any phonics program. My students are always getting stuck on one spelling of certain sounds. This gives them something simple to refer to when they are not sure which letter combination to choose. Sometimes my students will forget sounds that certain letter combinations make while they are reading. With these signs, they are much more confident when reading. This is a good resource for 1st through 3rd grade classrooms.
