In this little freebie you will find number cards 0-9. there are both large and small number cards. The small cards match the poster size cards. Number cards 0-4 feature number characters with “nice” faces. While the number cards 5-9 feature number characters with a “naughty” face. Nice numbers let the first number rest or stay the same. However, naughty numbers make the first number change up or get larger. I have also included a few pages for your students to practice estimation to the nearest 10, 100, and 1,000.
