Today’s lesson introduces students to the concept of magic squares, specifically focusing on a 3×3 grid. The main learning outcome is for students to recognize and demonstrate that more than two numbers can be added together, with the key rule being that the sum of each row, column, and diagonal should equal 15. Students are instructed to fill the grid using numbers 1 to 9, ensuring each is used only once, and the lesson includes tips for reusability of the templates, such as using laminated grids or placing them in plastic sleeves.
