CKMath Unit 6: Numbers 0–20
Focus:
In this unit, students count and represent collections of objects and images within 20. They apply previously developed counting concepts—such as one-to-one correspondence, keeping track of what has been counted, and conservation of numbers—to larger numbers. Students use the 10-frame to organize groups of 11–19 objects and images. This tool encourages students to see teen numbers as 10 ones and some more ones. Throughout the unit, students practice tracing and writing numbers 11–20.
