Question

What was the tool puritans used to teach their children? in addition to the alphabet, what else was taught using this tool?

Answer 1

I think that the tool you mean is a book. "The New England Primer". It was an educational book that was very popular between 17th and 19th centuries.

It was teaching the children to read, and at the same time, it was teaching them about the Bible - the primer contained some verses from the Bible.
