These calendar numbers are great for an ocean theme! They fit in a pocket chart calendar. There is a complete set (1-31) of each picture: rain cloud, umbrella, & rain boots. You can choose the pattern based on the level of your students: AB, ABC, AAB, ABB etc.
These numbers are also great to use in a math center for number recognition, number writing, number order, patterning, one to one correspondence, and sorting odd and even numbers.
