One of my favorite teaching tools is the wipe board. So cave man era, isn't it! I have one for each kid and just replace them halfway through the year or so when they are hard to erase (or get permanent marker on them by accident). They are only a few dollars now at your local big box store.
After some daily math this morning during table time, I used the wipe board to write some letters and then we used some picture cards and placed them by the corresponding beginning letter sound. Good times!
