Our Grade 9 students have explored the intriguing world of simultaneous linear inequalities. Far from arid pieces of abstract symbols on a page, students are discovering how these rich mathematical sentences allow us to model areas and solve challenging real-world problems.
To solidify their grasp and introduce some electrifying excitement to a familiar concept, they’ve taken classic Nonogram puzzles and given them an astronomical algebraic twist. Instead of simple, direct numbers, students are now using systems of linear inequalities to make arguments about how to complete cells, revealing their own unique, hidden images. This innovative approach deeply challenges their critical thinking, sharpens their graphing abilities, and radically highlights the visual power of algebra. It’s really great fun to watch them use such sophisticated reasoning to produce something so pleasing to the eye and satisfying!
