This puzzle can be used at a center to review density.
It comes with a set of 8 seperate task card puzzles with self checking QR codes.
Students cut out the “A, B, C, D” cards and place them where they think they belong based on the puzzle clues. You can give each child a set or laminate a set to use. I used Velcro to make an interactive board because my kiddos just love this center but it isn’t really necessary.
