# Math Lesson - Enrichment, One More and One Less, Kindergarten

In the "Enrichment" lesson, designed specifically for kindergarten students, we delve into the fundamental concept of "One More and One Less" within the realm of Counting and Cardinality up to 20. This lesson is a vital building block for young learners as it lays the groundwork for understanding basic addition and subtraction, which are key components of mathematical thinking and number sense.

Through engaging activities like the "3 Little Pigs Step Up Worksheet," students will practice identifying numbers that are one more or one less than a given number. This exercise not only reinforces their ability to count forwards and backwards but also introduces them to the principles of comparison and change in quantities.

Why is this important? Mastering the concept of "One More and One Less" is essential for developing a solid mathematical foundation. It enhances critical thinking and problem-solving abilities from a young age. Moreover, this understanding plays a crucial role in everyday life, helping students make sense of the world around them through numbers. By building their confidence in navigating numbers up to 20, we set them on a path of lifelong learning and success in mathematics.
