Teaching Base Ten is a Common Core must in math. It is a fun way to get the little ones understanding what numbers are all about. These Base Ten Number Cards display the Base Ten concept in ten frames and rods and units. They also show your students where to start writing the number! These number cards are a great space saver to an math board. As an added bonus, I have included a fun math mat that we use in class for a fun, interactive lesson on those troubled teen numbers. Enjoy!
