Tomb Robbers
Sixth graders examine benchmark angles embedded into a circle grid and examine how grid systems do not always have to be square. the game "Tomb Robbers" is used to develop strategies.
Curated OER
The Value of Volume
Students measure the perimeter and area of their polygons. In this geometry instructional activity, students calculate the volume and area using the correct tools. They calculate the time and temperature and the perimeter and side...
Curated OER
Tomb Robbers
Sixth graders identify benchmark angles as they are embedded into a circle grid. They observe the teacher using an angle ruler and complete a Star Spangled worksheet, play the game Tomb Robbers, and as a class discuss their game winning...

Opposite Angles in a Cyclic Quadrilateral
Learners investigate cyclic quadrilaterals in this geometry lesson. They use Cabri Jr to explore the sum of the measures of opposite angles in a cyclic quadrilateral. The dynamic nature of Cabri allows young scholars to form and verify...
Curated OER
Triangle Inequality Theorem
High schoolers investigate the relationship between angle measures and sides of a triangle and the relationships among the three sides of a triangle. The use of technology (Cabri, Jr.) allows learners to make and test conjectures as they...

Trigonometry
This unit covers the basic trigonometry including understanding radians, how to convert between radians and degrees, the area of a circle subtended by an angle, basic properties and graphs of sine, cosine, tangent, and solving...
Curated OER
Woody Sine
Students explore the concept of sine. In this sine lesson, students create a sine graph from tooth picks. Students create a unit circle with tooth pick length radius. Students then take the tooth picks from the unit circle and put them...
Curated OER
What's My BMI?
Students construct the Metric Pyramid from the handout. They use the Metric Pyramid to convert from standard to metric measure and vice versa. They compute their own Body Mass Index.
Curated OER
Metric Mania-Mass
In this metric system worksheet, students convert from the English system of measurement for mass to the metric system of measurement. They also convert measurements of mass within the metric system and explain how to measure an object...
Curated OER
Azimuth and Altitude Quiz 1
In this azimuth and altitude activity, learners answer questions about celestial bodies and how they are measured. They label drawings of clinometers, celestial spheres, and a compass.
Curated OER
Pairs of Angles
In this geometry worksheet, 10th graders determine the measures of various angle pairs: supplementary, complementary, and vertical angles. The two page worksheet contains a combination of twelve multiple choice and free response...
Curated OER
Sunshine Math-3
In this math applications worksheet, students solve 8 varied problems including consumer math, fractions, ordered pairs, measurement and mental math.
Curated OER
Metric Mania
In this metric system worksheet, students convert measurements of volume from the English system of measurement to the metric system. They also convert within the metric system and answer questions about volume measurements.
Curated OER
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
The Merry Go Round Problem
In this algebra worksheet, 9th graders analyze a concetric circle to determine the area a worker must paint in two different colors. They must decide from which angle he start painting because of the location of the merry go round. There...
Curated OER
Meeting in the Middle
Students view a video clip about the building of tunnels. They discover the importance of measurement and communication between groups when building a tunnel. They participate in an activity in which they must communicate with others.
Curated OER
Automobile-Accident Reconstruction
Students investigate an accident and relate it to math. In this trigonometry lesson, students measure the accident scene, the friction produced, and the speed from the skid marks. They create a poster of their findings.
Curated OER
That's So Square
Students familiarize themselves with the three most common geometric shapes: circles, triangles and parallelograms. They sketch, sort, and name the shapes.

"Sir Cumference and the First Round Table" by Cindy Neuschwander
Students study geometric terms related to circles and solve the problem posed in the book.
Curated OER
Time for Technology Glyphs
Students create a time for technology glyph using Kidpix4. They complete a circle map on things they like to do on while on the computer and write about their favorite thing to do while on a computer.
