This math unit begins by introducing students to calculating the area of irregular shapes on a grid, laying a foundation in basic area concepts using visual aids. It progresses to more specific geometric figures, starting with the area of rectangles, gradually moving towards applying formulas for various simple shapes like squares and triangles, reinforcing how to determine and apply area calculations using proper formulas. As the unit advances, learners explore area calculations for more complex shapes, including non-right triangles and parallelograms, highlighting methods to visualize these areas through equivalent simpler shapes like rectangles. This leads to a focus on calculating areas of trapezoids, which builds on previous knowledge by introducing approaches to treat trapezoids as equivalent rectangles. Students also learn to derive equations for the area of a trapezoid based on these concepts, evolving from basic application to more abstract and algebraic manipulation. The unit culminates in a comprehensive understanding of area across a variety of shapes and the translation of geometric understanding into algebraic expressions for real-world applications.Skills you will learn include:
