Print, cut, fold and glue or tape. Each page makes a 12-sided "die" consisting of subtraction problems, a different one on each die face.
One die has all the problems for a given number (e.g., 1 -1, 2-1, 3-1, 4-1...12-1) up to 12. There are 20 pages total (one for each number 1 through 20). Bigger number is always first so that the answer will always be positive (or zero).
Please download the free "Printable Foldable 12-Sided Dice" from my store and make sure you are able to print, cut and assemble properly before buying these, please! I want you to know what you are getting.
