This course contains 10 segments:

Area introduction

Area is how we think about how much space something takes in two dimensions, such as comparing how much land one property takes up versus another. In this tutorial, we'll take a look at how area is measured.

Count unit squares to find area

Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area. Create rectangles with a given area by covering unit squares.

Area formula intuition

Count unit squares to find area

Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area. Create rectangles with a given area by covering unit squares.

Area formula intuition

Transition from counting unit squares to multiplying side length to find area. Measure side lengths with a ruler to find area.

Multiply to find area

Find area of rectangles by multiplying side lengths. Find a missing side length of a rectangle when given the other side length and area. Compare areas of rectangles presented in images or contexts.

Area and the distributive property

Use the distributive property to find area of rectangles.

Decompose figures to find area

Decompose figures into two to three rectangles to find area of entire figure.

Perimeter

Have you ever wondered how much fencing you need to surround a plot of land? No? Well, you should still go through this tutorial just in case. You'll learn what perimeter is and how to calculate it.

Comparing area and perimeter

Compare the areas and perimeters of rectangles when given a context or picture.

Perimeter word problems

Solve real world problems problems involving perimeter.

Quadrilaterals

Classify quadrilaterals, including rectangles, rhombuses, and squares. See what attributes they have in common and which ones make them unique.
