C1. Algebraic Expressions and Equations
C1.1 research an algebraic concept to tell a story about its development and use in a specific culture, and describe its relevance in a current context
C1.2 create algebraic expressions to generalize relationships expressed in words, numbers, and visual representations, in various contexts
C1.3 compare algebraic expressions using concrete, numerical, graphical, and algebraic methods to identify those that are equivalent, and justify their choices
These two lessons introduce students to algebra tiles and use them to visually understand the distributive property. The content is based on lessons developed by Jackie Decker (a fellow Ontario educator) and link to her brief YouTube videos that walk teachers through these activities and give excellent teacher tips to help develop and consolidate student thinking. These printable teacher guidelines summarize Jackie’s suggestions and also link to a Desmos Activity that can be copied and used to facilitate each of these lessons.
C1.4 simplify algebraic expressions by applying properties of operations of numbers, using various representations and tools, in different contexts
C1.5 create and solve equations for various contexts, and verify their solutions
