Exploring Grade 6 Mathematics: Unit 2 Concepts

This lesson focuses on teaching grade six students about unit rates and equivalent ratios using double number lines. The video includes a number talk on mental strategies for finding quotients, followed by practical examples involving the cost calculation of avocados, water bottles, and flour. Students are encouraged to use double number lines to solve these problems. The lesson concludes with group activities and practice problems to reinforce the concepts learned.
