Check out these word builder slides. All it took to make them were some paint sample cards and a permanent marker. The nice folks at my neighborhood Wal Mart gave me the paint sample cards. I needed about 35 (2 3/4 x 5 1/2) single colored cards and 15 (2 x 9) multi colored cards.
I wrote word families on the large cards and beginning phonemes and diagraphs on the multi colored cards. It took about 15 minutes to make. Easy peasy!
