This fun, St. Patrick's Day themed math center, focuses on number sense. The matching game is flexible and adjustable to the needs of your students. I would recommend creating the games with numerals 1-5 and 6-10, separately, to keep the games from being overwhelming. There are six different representations of numerals 11-20. Use all six or pick and choose what fits your needs. Choose 2, 4 or 6 representations, in order for students to match up pairs. Recommended for 2-4 students. Color and
