Ancient Egyptian's had a fantastic number system and your class gets to use it to practice basic math skills! They are presented with several examples of Egyptian numbers which they use to complete several addition and subtraction...

For use with a TI-nspire calculator, this lesson focuses on adding and subtracting polynomials. Learners use calculator to add and subtract polynomials using both the vertical method horizontal methods. A class discussion follows the...

High schoolers listen to a lecture and complete a number of problems as they go. There are a variety of examples given and they are guided through the problem solving steps for each of the real-world scenarios regarding the purpose of...

The class examines graphs in the form r = F(¿¿) in polar coordinates (r, ¿¿), in particular with the circle, ellipse and other conic sections. They determine the nature of an ellipse by studying the role of the semimajor axis and...

Learners identify names of angles. They use a large clock to demonstrate angles using certain times of day. Given a geoboard, students create figures with acute, right, and obtuse angles.

Students examine American coins. For this American currency lesson, students study how American money came to be as well as the responsibilities of the U.S. Mint. Students discover details regarding American coins and design their own...

High schoolers explore the possibility of being on Mars and being able to identify the Earth.  In this space lesson students complete a set of calculations to see if this is possible. 

Students examine the relationships among living and non-living parts of the environment. Using their senses, they identify the objects in their classroom. In groups, they participate in experiments to discover where electricity comes...

Learners see that light and heavy objects fall at the same rate, as established experimentally by Galileo. They see that falling objects, and balls rolling down an incline, tend to accelerate at a constant rate a. Their velocity...

Students engage in an overview of the story of Tycho Brahe and Johannes Kepler, and of Kepler's laws. Each of Kepler's laws be studied separately in more detail in later lessons. They examine Kepler's 3rd law.

Students engage in a historical review, starting with the existence of the horizon at sea, proceeding to various studies of the Earth's size and shape, and leading to the attempt by Columbus to reach India by sailing westward.

Fifth graders study probability of events. They predict outcomes, and participate in hands-on experiments to find the probability of specified events. Afterward, 5th graders write probability of events in fractions and decimals.

In this real world work worksheet, students solve word problems that contain concepts such as miles, money, paper, and more. Students solve 6 problems.

Fifth graders create math word problems. In this geometry lesson, 5th graders define perimeter and discover how to find the perimeter of a rectangle, a square and a regular polygon. Students write word problems on finding the...

Students gain an understanding of Kepler's 2nd law--that planets (and satellites) move fastest at their closest approach to the center of attraction, and slow down when far away. They explore the concepts of "potential energy" and...

Students explain that planets actually orbit the center of gravity of the solar system, and that distant planets may be detected by motions of their central star around the centers of gravity of their planetary systems.

Students become acquainted with linear graphs, the parabola and the rectangular hyperbola. Also prepare tables of paired values as preparation for plotting a line. They study the cartesian equation of an ellipse, with a worked example.

Students examine total eclipses of the Sun and their limited regions of totality. They explain that this limited view occurs because the Moon is close enough to us for different points on Earth to view it differently.

High schoolers discover how Aristarchus, a Greek astronomer around 230 BC, used a simple observation of the eclipse of the Moon, plus clever reasoning, to deduce the distance of the Moon. They practice the same calculation technique.

Students discover how astronomers used the diameter of the Earth's orbit around the Sun as a baseline for estimating the distance of some stars, and the meaning of "Parsec" and "light year."

Students use cartesian coordinates (x,y,z) in 3-dimensional space. [Optional: appreciate there exist two ways of defining the z axis, and which of them is used.] They become familiar with the tools and terms used by surveyors.

Students study the basic methods for finding one's position on Earth. Latitude can be deduced from the height above the horizon of the pole star or of the noontime Sun, while longitude requires an accurate clock giving universal time.

Learners explore linear graphs, the parabola and the rectangular hyperbola.

Young scholars use Kepler's third law to derive the velocity in a circular orbit of any radius, and identify the Earth escape velocity.
