Another saying for phonetic spelling is "invented" spelling. I don't remember this learning concept from when I was in the first grade ... well that was so 1975 ago.
I had a little misinterpretation here with peshit. As long as your child can read his or her own writing back to you, they are learning how to spell. Thankfully he read 'pesnit' as President and 'pert' as "pertected". About George Washington, "He was the first President and he pertected us."
Here's the thing... Phonetically speaking, I can't read.
