It helps students practice mental math skills and become more fluent in making quick calculations involving tens. The use of symbols (+10 or -10) introduces students to basic algebraic thinking, connecting visual cues to arithmetic operations. Additionally, the self-assessment section at the bottom encourages students to reflect on their learning and understanding of the concepts.
