Goal | Standard(s) | Objective(s) |
Mathematics 5-8 Have students understand and explain that many different triangles can have the same area. | MN Mathematics 5.3.2.1 Develop and use formulas to determine the area of triangles, parallelograms and figures that can be decomposed into triangles.
NCTM grades 3-5 Measurement Explore what happens to measurements of a two-dimensional shape such as its perimeter and area when the shape is changed in some way.
| 1) Using a sheet of grid paper, students will be able to draw six differently shaped and oriented triangles (including acute, right, and obtuse examples) that all have the same base and height measurements. 2) Using triangle diagrams and referring to measurements and the triangle area formula, students will be able to explain how different-looking triangles can have the same area.
