All you need to teach phonics! Put in the DVD and the bingo-like playing cards and that's it! This DVD is compatible for a computer or DVD player. It has a menu that allows you to click on any letter of the 99 phonetic sounds. Just press play, and in less than 30 minutes, students will see and hear all 99 letters/sounds of the English language. They will also trace the letter/sound if found on their playing card.
