This is a basic set of addition flash cards, 0-18. I used an American Sign Language Font, I do not know ASL myself. The cards are perfect for students to keep in their desk, chairback, math kit, etc. They are also perfect for printing and sending home for practice. I recommend printing on cardstock and having the students or the parents put the answer on the back. There is a set of these cards with numbers as well, but I thought sign language would be beneficial. Please let me know if this product does or does not work for you. I can make changes as needed. Thank you for your purchase.
