Measurement and Geometry: Resources for Adult Educators

Special Collection

This collection of video segments produced by KET provides resources for teaching measurement and geometry in the adult education classroom. In this collection, you will find individual lessons tailored to specific geometric concepts such as naming angles, finding area, and calculating volume. Each resource contains a video clip accompanied by a printable background essay and suggested discussion questions. Most resources also include teaching tips for application in your classroom.

RESOURCE GRADE LEVEL MEDIA TYPE

Angles - Acute, Obtuse, Straight, and Right

Angles are measured in degrees. These measures are used to classify angles as acute, obtuse, straight, or right.

9-12

Video

Angles - Complementary and Supplementary

Understanding complementary and supplementary angles will help you solve for an unknown angle measurement.

9-12

Video

Angles - Naming

There are three ways to name an angle.

9-12

Video

Angles - Parallel Lines Crossed by a Transversal

Although parallel lines never meet or cross, they can be intersected by one or more lines called transversals.

9-12

Video

Angles - Right and Obtuse

Angles are measured in degrees. These measures are then used to classify angles as acute, obtuse, straight, or right.

9-12

Video

Angles - Vertical and Congruent

Vertical angles lie diagonally opposite one another at an intersection. Vertical angles are equal in measure.

Video

Converting English Units of Measurement

In many situations you encounter in daily life, you need to convert (change) a measurement from one unit to another.

9-12

Video

The Coordinate Plane

The coordinate plane is a flat surface that is divided by two number lines into four quadrants.

9-12

Video

Counting and Measuring

Numbers are used to count and to measure. We use numbers to talk about time, distance, size, and weight.

9-12

Video

English and Metric Measurement

Both English and metric measurement systems are used to measure length, weight, and volume (how much something holds).

9-12

Video

Equivalencies and Benchmarks

Knowing basic equivalencies and benchmarks will help you with measurement.

9-12

Video

Finding Area

Area is measured in square units. Multiply the length times the width to get the square units.

9-12

Video

Finding the Area of Irregular Figures

Area is measured in square units. Partition irregular figures into regular shapes first to find area.

9-12

Video

Finding Volume

Volume is the measure of how much space there is within a three-dimensional object.

9-12

Video

GED Formulas: Isolating the Variable

To solve for a “missing” dimension, you need to use an algebraic strategy known as isolating the variable.

9-12

Video

GED Formulas: Using Variables

A variable is a letter or symbol that takes the place of a number. Variables are used in formulas to solve problems.

9-12

Video

The Language of Geometry

In geometry, familiar words have very specific meanings.

9-12

Video

Metric Units and Prefixes

The metric system of measurement is based on tens. Use metric prefixes to name larger or smaller units.

9-12

Video

Pi, Circumference, and Radius

Understanding pi, circumference, and radius will help you measure the distance around and surface within a circle.

9-12

Video

Slope

Slope is the measure of the incline, or steepness, of a line.

9-12

Video

Solving for X and Y

The relationship between the ordered pair of x and y allows you to solve equations with two variables.

9-12

Video

Triangles - Isosceles and Scalene

An isosceles triangle has two equal sides and two equal angles. A triangle with no equal sides or angles is called a scalene triangle.

9-12

Video

Triangles - Sides and Angles

All triangles are composed of three sides and three angles.

9-12

Video

Triangles - Similar

Similar triangles have the same shape, but they are not necessarily the same size.

9-12

Video

Triangles - The Pythagorean Relationship

The relationship between the length of the hypotenuse and the legs of a right triangle is called the Pythagorean Relationship.
