This math unit begins by introducing and practicing perimeter calculation, first with rectangles and progressing through various shapes including triangles, parallelograms, kites, and trapezoids. Initially, students learn to compute perimeters using visual diagrams and multiple-choice answers, allowing them to develop and strengthen their understanding of measuring linear boundaries in diverse scenarios like gardens or parks. As the unit progresses, the focus shifts towards more complex shapes and tasks, such as calculating perimeters on grids and handling different units of measurement, further enhancing students' spatial visualization and practical measurement skills. Towards the latter part of the unit, the emphasis transitions to area calculation, starting with parallelograms and trapezoids, and evolving to include right and non-right triangles on grids. This requires students to apply previously learned concepts in perimeter to understand and compute areas, using methods such as grid counting or decomposition into simpler shapes. By concluding with the task of finding the area of non-right triangles through visual manipulation of rectangles, the unit builds a comprehensive foundation in both perimeter and area calculations, crucial for practical applications in geometry.
