Here we have prepared addition equation cards I created for my Lower Elementary Montessori classroom. This set includes static two digit, three digit and for digit addends. There are eight of each kind, a total of 24 prepared equations. Answer Keys are included. Being a Montessori teacher the cards are color coded; ones are green, tens blue, hundreds red, and thousands green. My students use these while working with the checker board, golden beads, stamp game and bead frames.
