2 years ago I had the Sunday school kids make a banner. all us teachers had the kids memorize how many books were in each testament, we eventually had them memorize all the books we had roughly 6 kids say every single book from genesis to revelations :) we had about 5 memorize the old testament. :) kids absorb more than you think! my cousin was the youngest one of the 6 and she was 4yrs old at the time till this day she still can name all 66 books and shes still learning to read! I am proud of all the kids maybe this year we will get our new kids to learn the books
