About Addition within 20
Sets are numbered, and each uses fresh numbers on the same skill, so you can repeat the skill without repeating a page. One set is free and the rest cost 1 credit, about $1. They are PDFs for printing at home or in your own classroom, and the Personal licence covers your own classroom and home.
Questions people ask
Is there an answer key?
Yes. Every worksheet ends with a separate answer key page, so you can print the problems and keep the key for yourself.
