This is what I have on my kitchen wall.

I (like the rest of you) am really busy and practicing letters and numbers is sometimes the last thing on my mind! I keep these up so that while I am making meals I have have Trevor spell is name tell me the letters and sounds and numbers. It is right there to remind me ready to go and no extra work for me!!!
Although we teach the uppercase letters first. I encourage you to teach your child the correct form of their name from the start. This way they do not have to relearn their names.

Work on what is appropriate for your child! Add letters and numbers as they are ready!
