Globe Skills Lesson 3 Voyage to the New World
Middle schoolers explore the globe. In this globe skills lesson, students use their knowledge of latitude and longitude to respond to questions regarding Christopher Columbus's maiden voyage to the Americas.
Curated OER
Angle Land and Angle Aerobics
Sixth graders investigate different types of angles. In this geometry lesson, 6th graders use a protractor to identify acute, obtuse, and straight angles.

Azimuth and Altitude
In this azimuth and altitude worksheet, students answer fifteen questions about measurements of objects in the sky using a compass and an inclinometer.
Curated OER
Orienteering I
Learners are introduced to compass work. They name the parts of a compass. Students describe how the parts of a compass are used. They are shown the proper way to hold a compass. Learners are shown that-a-way arrow and its purpose.
Curated OER
Orienteering II
Students name the parts of a compass and comprehend the function of each part. They define paces and tallies and use them in a real world situation. Students are shown the proper use of radio terminology. They use a map and compass to...

Geometric Probability
In this geometry worksheet, 10th graders determine the probability of an event occurring based on the geometric sketch. The one page worksheet contains fourteen problems. Answers are included.
Curated OER
Artistic Angles
Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...
Curated OER
Tessellations: Use Angles To Show That Shapes Will or WIll Not Tessellate
Learners observe a selection of shapes. They identify which shapes will tessellate and justify their answer. Students apply the symmetry and angle properties of polygons to create tessellations.
Curated OER
How Many?
In this how many activity, students answer how many are in a pair, dozen, weekend, tandem, and other numbers. Students complete this for 10 problems.
Curated OER
Clocks and Time
Students construct clocks and then learn how to read a clock face, tell time, and determine how much time has elapsed.
Curated OER
Parallax
Young scholars 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."
Curated OER
Graph Both Crusts
Fourth graders calculate the angles and construct a pie graph of the percentages of the elements in the continental and oceanic crusts. Then they analyze the results. They can be assigned the task of researching the percentages.
Mathigon
Mathigon: Geometry: Circle and Pi: Degrees and Radians
Rather than dividing a circle into some number of segments (like 360 degrees), mathematicians often prefer to measure angles using the circumference of a unit circle - a circle with radius 1. This way of measuring angles is called...
National Council of Teachers of Mathematics
The Math Forum: Ask Dr. Math: Degrees in a Circle
Dr. Math answers a students question as to why a circle contains 360 degrees.
