Help needed - Book/worksheets of beginner to intermediate chess puzzles for elementary students

Hello everyone! I'm excited to be volunteering to run a chess club at an elementary school (K-6). I'm a beginner myself, with a rating below 1000. Last year, when I led the club, I used lessons from ChessKid's curriculum for a few minutes before we had open play. Many students enjoyed the lessons and simulations I presented on an overhead projector.

Since we'll have students with varying levels of experience, ranging from no knowledge of the game to those who have played in tournaments, I want to set up some puzzles for them to solve on chess boards. Can you recommend any books or worksheets that I can use to create puzzles for them to solve, as well as workbooks for those who want to work on chess problems without a board?
