Great for math centers!
This is 20 different "addition tower" problems: it combines Basic Set of Addition Towers
and adds 10 more puzzles that use various combinations of digits to make the totals located at the base of each tower. Cut out the digit cards and place them directly on to the puzzle sheets until they get a solution and then record them on the answer sheet.
Includes recording sheets so that you don't have to print up individual sets for each student, and a "DIY" sheet so that you can make your own problems.
