These number cards are specially sized to fit perfectly in your hundred pocket chart. They are color coded to aid students in skip counting by 2's, 5's and 10's, and are easy to read. The number cards could also be used as part of a math center to help the students sequence their numbers or do number comparisons. Lots of options on ways to use them! If you are planning on using them in a center, I recommend laminating the cards. Otherwise, just print on heavy or card stock paper, cut apart and you're all set!
