This collection of 10 worksheets focuses on the CCSS of counting and cardinality. It requires that a student can count from 1-20 and record the last number counted. I require that my students label each object as they count for the purpose of keeping track (later you can introduce grouping by 2s, 5s, or 10s in their counting and labeling). The worksheets begin with linear rows of objects and then range in complexity to objects obscurely arranged.
Use as homework, morning work, exit tickets, independent work, and remedial math work.
