Practice Counting Objects to 20

Khan Academy

This educational video guides young learners through three distinct counting exercises designed to reinforce early numeracy skills and one-to-one correspondence. The narrator demonstrates how to count sets of objects—specifically whales, sheep, and flowers—ranging in quantity from small groups (5) to larger sets (17). The video models the process of checking multiple options to find the correct answer and demonstrates how to count organized arrays of objects systematically. The content focuses on key early math themes including counting to 20, cardinality (understanding that the last number counted represents the total quantity), and visual discrimination between different group sizes. It explicitly demonstrates the strategy of counting aloud and touching or pointing to each object to ensure accuracy, a fundamental skill for Kindergarten math fluency. For educators, this video serves as an excellent model for explicit instruction in counting strategies. It can be used to introduce a math lesson, as a guided practice activity where students count along with the narrator, or as a tool for addressing misconceptions about guessing versus verifying quantities. The visual structure—showing objects in rows and grids—also helps build the foundation for understanding arrays and future multiplication concepts.
