For a fun spin on the traditional game of "Memory", play this game to work on number recognition and matching quantities to numerals (0-20). Print off the following number/dot cards. Then lay all the cards face down on a flat surface. Students will take turns flipping over two cards at a time to create a match between a number and a quantity. Whoever gets the most matches wins! Choose the numbers and quantities you need in order to differentiate for your students' needs.
