Composing and decomposing numbers represents a foundational mathematical concept that builds essential number sense and computational fluency in elementary students. These carefully designed presentations available through Wayground provide structured instruction that helps students understand how numbers can be broken apart and put back together in multiple ways, supporting their development of flexible thinking strategies for addition and subtraction. The visual learning materials offer concept explanations that demonstrate various decomposition methods, from breaking numbers into tens and ones to exploring different additive combinations that equal the same sum, enabling students to develop deeper mathematical reasoning and problem-solving capabilities. Wayground's extensive collection of teacher-created presentations draws from millions of educational resources specifically focused on number composition and decomposition strategies. Teachers benefit from robust search and filtering capabilities that allow them to locate materials perfectly aligned with their curriculum standards and student needs, while customization tools enable differentiation for learners at various skill levels. The platform's digital-first delivery format supports flexible implementation across whole-group instruction, small group work, and individual practice sessions, making these presentations invaluable for initial concept introduction, targeted remediation for struggling learners, and enrichment opportunities for advanced students seeking to strengthen their foundational number sense skills.
