What educators are saying

This is a great resource for practicing perimeter and area. No prep needed and rigorous enough for all students. Very clear explanation for the area of triangles.

Description

Measurement & Formulas: Calculating Perimeter and Area of Rectangles & Triangles • SEMiPRO Elementary Montessori-inspired Geometry help (4 printable pages + key):


Explore the perimeter and area of polygons. These pages guide young geometrists to:

  • Review the geometric terminology for rectangles and triangles
  • Follow a step by step guide for measuring perimeter of rectangles & triangles with examples using Montessori's yellow area material
  • Introduces students to the formula for area of rectangles and triangles
  • Understand why the unit of measurement for area is squared.

How do we explore geometric shapes? Explore polygons, their terminology and characteristics. Follow a step by step guide to measuring the perimeter of rectangles and triangles. Finally, the formulas for area of both shapes are introduced. Examples are included using Montessori's yellow area material. Enjoy Measurement & Formulas: Calculating Perimeter and Area of Rectangles & Triangles!

Dr. Maria Montessori believed the only way our world would find lasting peace was through educating our children. Much of her elementary curriculum was written by her during a period of internment in India during WWII. This time period helped solidify Dr. Montessori’s belief in Peace Education.

Standards

to see state-specific standards (only available in the US).
Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
