problem_activity: Narrative
The purpose of this warm-up is for students to extend the verbal count sequence to 30. Students also see the numbers written as they say each number to help connect the number names to the written numbers. In the synthesis, students determine the next number in a count, which prepares them to count on from a given number. This deepens their understanding of the structure of the counting sequence (MP7).
