Does Your Field Measure Up

Get out those protractors! From any angle, this worksheet will give your mathematicians some good practice. First, they find the measurement of eight angles. Next, they draw eight angles given the measurement. 

Learners explore mean, median, and mode as they model mathematics in real-world problem situations. The lesson requires the use of the TI 30X IIS.

A baseball trajectory and a parabola seem to make the best pair in real-world quadratic applications. Here is a current baseball resource with questions, discussions, and explorations regarding a quadratic function and home run...

Forest industry professionals make measurements in their work using tools including the Clinometer and the Biltmore Stick. These tools are based on the concepts of similar triangles and trigonometric ratios in a right triangle. This...

Geometry—it's not just for the math classroom! Learners explore the field of forestry through a mathematical lens. An instructional resource explains how forest workers collect data about trees such as height, diameter, and age...

Students keep track of the number of tosses it takes them to reach each base, and encourage team members and recognize their successes. To make this activity fit the level of older classes, measure distances and figure averages as you play!

Surveyors describe land parcels with distance and angle measurements, often given as compass headings. Once the boundaries of the land parcel are described, the surveyor can calculate the area of the land. This activity uses Cabri Jr....

When hikers and skiers go into terrain with a risk of avalanches, they take safety equipment including avalanche rescue beacons. An avalanche rescue beacon sends and receives electromagnetic field signals that travel in circular...
