K.CC.A.1 Worksheets: Count to 100
Home › Common Core › Kindergarten Math Standards › K.CC.A.1 Worksheets
K.CC.A.1 (Counting and Cardinality): Count out loud to 100 by ones and by tens.
About this standard
Most children can chant the tens long before they can count by ones across a decade change, so 29 to 30 and 79 to 80 are the spots to listen for. Count together while climbing stairs or setting the table, starting at a different decade each time. Use Counting to 100 by Ones and Tens for both kinds of counting, and see K.CC.A.2 for counting on from any number.
