These are large, brightly colored, calendar pieces to be used for math in Kindergarten and 1st grade. They are designed based on common core standards. Students may practice identifying and describing 2D and 3D shapes, identifying coins and their values, and various counting strategies including counting on, counting by 5's and 10's and doubles. This spiraling of common core standards will increase student knowledge of mathematics and its vocabulary. Look for more by Nelson Bonn.
