This is an ABC chart that I hang up in our Kindergarten Room but can be used in first grade rooms as well. How it works is every morning after we finish circle, my helper of the day/week will go over to the chart and with a pointer will start at A and go "A is for apple, /a/ /a/ /a/. (So they are saying the sound three times). They go through all the letters and the 4 blends. We practice this chart everyday and once the kids got good, I taught them sign language letters to do while we say it.
Besides the poster to display in your wall, also included with this is a one page chart with all the same pictures to laminate and put on student tables for them to reference when they are writing. It has upper and lower case letters.
