I used this as well, but I had an older child at the time. We really enjoyed it. He would make up sentences using the words and I would quiz him on the meaning. We used it with MFW a few years ago. I am going to use it again with my younger child and will probably use matching game and bingo with it as well.
You could put the cards into a small paper bag, have him pick out a card and make up a sentence orally with the word.
You could also have him draw pictures of the words. Also having a “word of the day/week” and look for that word in use out and about.
