This Problem Set is a part of the Lesson 16, Unit 5, Grade K. In this lesson, students work to know the number names and the count sequence. They count within tens by ones up to 100. They use counters and 10-frames to count 1-9, add another 10-frame, and continue building numbers within tens by adding 9 ones to build understanding of numbers beyond 20.
