This smart board lesson correlates to the EngageNY Module 1: Lesson 3. It includes a "DO NOW", educational video on concept being taught, whole group instruction, group work and independent work. A "Wrap Up" slide is included as a closure to the lesson.
Each slide sequentially follows the engageny lesson plan.
Students develop an intuitive understanding of equivalent ratios by using tape diagrams to explore possible quantities of each part when given the part-to-part ratio. Students use tape diagrams to solve problems when the part-to-part ratio is given and the value of one of the quantities is given.
Students formalize a definition of equivalent ratios: Two ratios, A:B and C:D, are equivalent ratios if there is a positive number, c, such that C = cA and D = cB.
