This math topic focuses on helping learners master the skill of making ten to reach the next ten within the context of one-digit integers, specifically under the total sum of 30. It emphasizes mastery in recognizing how many more units are required to complete groups of ten, using simple integers (less than 30) and various geometric shapes (such as circles, triangles, and squares) to represent quantities visually. This skill development is instrumental in enhancing mental calculation speed and accuracy in basic addition, laying foundational arithmetic principles.
