The Abeka Flash-a-Card Jacob is a set of 15×12″ cards featuring lessons from the Abeka curriculum. Included in the set are two teacher’s books to guide instruction. These are the true flash cards and not the cheap paper junk Abeka now sells for a premium! I ordered these by mistake thinking that I needed them but realized, too late that I already owned a matching set! These flashcards are designed for educational purposes, making it easy for teachers to present and review lessons with students. With the convenience of flashcards and the added support of teacher’s books, this product is a valuable resource for educators looking to enhance their teaching materials.
