This was created to be a math center in my kindergarten class. Laminate and cut out the cards so they will be durable with little hands. Students will recognize the number represented with the base ten block cards and match them to the correct numeral card. The common core standard has the students decomposing numbers 11-20 and demonstrating it with pictures and drawings. I have included 0-30 in base ten blocks and numerals. The 21-30 cards can be used for enrichment.
