I created these sheets to use during centers. I printed them front/back and laminated them so they could be used over and over. These could also be used in whole group or as an assessment.
These sheets progress for differentiating. These start with numbers to 10, then numbers to 20, and numbers to 30.
Common Core connection:
K.CC.4 Understand the relationship between numbers and quantities; connect counting to cardinality.
K.CC.5 Count to answer "how many?" questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.
