When I introduce vowels, I tell my kids they’re the glue that holds our words together. I’m sure you do the same thing, too! I found these great vowel glue bottle posters from the talented Teacher Wife about 5ish years ago and have been displaying them in my classroom ever since. They go right in the middle of my phonics posters behind my guided reading/small group table.
While most of my short vowel instruction is done during whole group shared reading/writing experiences, I reinforce those concepts during small group and independent centers as well. Repeated practice is so important and I want my kids to have TONS of it!!
