here are some things my mother and i did to try to teach me to spell, they sort of worked.

Get a dark black cookie sheet and cover it with salt- have the child write the word in the salt while singing the letters and then singing the word. It is supposed to attack many of the senses at once.

Have the child crawl around while singing the letters to the word.

Hold a mirror up to the child as they are writing the word in thick maker on white paper- have them look in the mirror, they write the word and you say the letters together.

None of those methods were that effective.... when we did them we did notice a small bump in my scores on spelling tests. I would get one or 2 extra words correct. It bummed me up from a "F" to a "D" or "C".
