I made this at www.wordle.net By typing in my blog site, the words that I used the most in my entire site came up the largest. It kind of shows the priorities that I write about in my posts.
My son used the site with his spelling words. He typed them instead of writing them for his homework. This is another fun way to infuse paper-pencil homework with technology. When my daughter was in first grade, her teacher also allowed her to type her spelling words, instead of hand write them. Then, I helped her to email them to her teacher. She loved it and it made her feel so grown up!
