I don't know about your little one, but ours...not a fan of spelling practice. I've tried a bunch of different ways to practice; rainbow words (each word written in a different color), sentences (zero fun), white board, drawing what the words are with the letters (fun, but not really effective), etc., etc. But I think I have come up with something that has made her happy and has resulted in her actually remembering the words in her other writing projects. Writing in salt. Yep. That's it.
I had an old blue drawer organizer thing (it should be a dark color) and I just threw some salt in it. She draws the words in the salt, shakes it, doodles, draws another word...you get the idea. Fun, cheap, and effective (at least for her).
