I don’t have any games, but I’ll share an activity my boys loved when they were little. Writing words, even three-letter words, was such a chore. But I bought a big plastic bin of colorful magnetized letters and a great big cookie sheet. When we’d discuss spelling, we’d use the magnets. I’d group some basic consonants, and some vowels, and maybe start them with a simple word like “pat” and then ask them to make “mat” That kind of thing. For some reason they loved it. Or I’d put up part of a word and ask them to finish it (at first I’d make sure there was a small group of letters that would finish it so they could have “success” quickly) If they had trouble, I’d spell it for them, and we’d practice “taking a picture” of it, then I’d remove a letter and ask them to “see” it with the letter removed, etc. Worked for us, anyway.
