Use this growing number line to count the days of school with your class. These fish can be displayed in a line format or in a hundred chart. Reinforce counting by 1's, 5's, and 10's. All 5's are boxed in green and all 10's are boxed in orange to aid students when skip counting. This free sample includes numbers 1-30. Please check out the full package, numbers 1-180, in my TpT store.
