This product can be used for a quick and easy lesson or math center. The product includes eleven pages (numbers 10-20) of 4-piece puzzles showing different representations of each number: objects, tally marks, the numeral and ten frames. If students are in younger grades, only puzzles for specific numbers can be used. The puzzles can be copied and consumed as one-time use for students, or they can be copied onto card stock and laminated to be used again and again, year after year.
