I only work one on one. I give one of these to each of my students when they begin their Hebrew studies. I also use it during lessons with letter magnets - I have the student match the magnet letters with those on the placemat. This game reinforces the small differences in each letter. I have added the "twin" names under Bet/Vet, Kaf/Chaf, Pey/Fey and Shin/Sin with a sharpie. Thank you for providing me with this useful product.
