Video Learning Notes
Students learned to use models to understand and derive formulas for the perimeter of rectangles and squares and the area of rectangles. They practiced calculating perimeter and area using these formulas and solved problems involving whole number dimensions. This lesson builds foundational algebraic reasoning skills by connecting visual models to mathematical expressions and problem solving.
Learning Goals
- Use visual models to derive the formula for the perimeter of a rectangle (l + w + l + w or 2l + 2w).
- Identify and use the special perimeter formula for a square (4s).
- Use visual models to derive the formula for the area of a rectangle (l × w).
- Solve problems involving perimeter and area of rectangles with whole number dimensions.
