Lesson plan in which students calculate area, build areas to a given amount, and calculate the perimeter with the use of Legos. Step by step instructions and videos are provided. CCSS.Math.Content.3.MD.C.7.c Use area models to represent...

This lesson plan presents the idea that the area of any right triangle is exactly half of a certain rectangle, and contains varied exercises for young scholars.

This task is a natural follow up for task Rectangle Perimeter 1. After thinking about and using one specific expression for the perimeter of a rectangle, they now extend their thinking to equivalent expressions for the same quantity....

This fifth-grade lesson explores the area of a rectangle with fractional side lengths. We tile the rectangle with unit rectangles and show that the area is the same as would be found by multiplying the side lengths. We multiply...

In this task, students must draw a diagram from a verbal description and use their understanding of similar triangles to find the area of a quadrilateral. Aligns with G-SRT.B.5.

This tutorial provides a brief introduction about what area is, then gives the formulas for area of a square, rectangle, parallelogram, trapezoid, triangle, and circle. Examples of each formula are provided.

This activity operates in one of two modes: auto draw and create shape mode, allowing you to explore relationships between area and perimeter.

Explore the world of quadrilaterals and their properties. Find answers to questions like what are quadrilaterals, how they are formed, easy ways to identify them, and commonly seen quadrilaterals around us.

The resource consists of student notes, instructor notes, and an interactive activity. The activity allows learners to find the factors of a given number and then draw the product as the area of a rectangle on a grid.

Calculate certain variables of a parallelogram depending on the inputs provided. Calculations include side lengths, corner angles, diagonals, height, perimeter, and area of parallelograms.
