So, do you work on typing in your class? I do... a lot! For some of my students I feel that typing is a more appropriate means for writing. For some reason, the "space bar" is always a tricky one. For my students that are learning to type simple sentences or even typing a few sight words, they always get confused on what to do when they finish the word.
I added stickers to ALL of my keyboards in my classroom. This way when we are typing they can remember to find the "star" or "happy face" or "soccer ball" in between the words! This has made a HUGE improvement in my students learning to type independently!
