Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Earth science super stars visit the National Earth Science Teachers Association's interactive website to glean information on the layers of the atmosphere. Data tables are provided for them to record what is collected. This assignment...

Students estimate the altitude of a rocket during several flights. They create their own altitude tracking devise. They examine and discuss their results at the end of the activity.

Learners analyze graphs and make conclusions about climate change.  In this climates lesson students produce graphs and identify relationships between parameters.

High schoolers calculate the altitude of triangles.  In the web based lesson, students explore the interior distance from a given point in a polygon to its side.  They compute the sum of these lengths. High schoolers read...

Students draw perpendicular bisectors.  For this perpendicular bisectors lesson, students identify the perpendicular bisector in a polygon.  They use web tools to create and measure perpendicular bisectors.  Students...

In this geometry worksheet, learners identify the altitude, perpendicular bisector, median, angle bisector and the area of different polygons. There are 33 problems.

Young mathematicians explore the concept of triangles as they construct altitudes of triangles to find the orthocenter. Learners construct their triangles using Cabri Jr. on their graphing calculators and find that the altitudes of a...

In this mountaineering and acclimatization worksheet, high schoolers read about the changes that take place in the blood as the body acclimatizes to high altitude. They answer three critical thinking questions about acclimatization.

In this constellation worksheet, students pick a constellation to track over time. They measure its altitude and azimuth at least three times. They make an experimental design for their research and plot their data.

In this angle measurement worksheet, 10th graders solve and complete 9 different word problems. First, they read the word problems carefully. Then, students draw a picture that represents each problem and solve. Finally, they find side...

In this right triangles worksheet, 10th graders solve and complete 13 different problems. First, they find the lengths of both missing sides. Then, students find the altitude of an equilateral triangle given the measure of one side. They...

In this similarity activity, 10th graders solve and complete 14 different types of problems. First, they find the length of each segment given two lines parallel. Then, students find the measure of each segment of a parallelogram...

In this analysis review worksheet, students solve 3 complex inequalities, graph 2 absolute value inequalities, and write the equations for altitudes and tangent lines for 4 problems.

Students examine the potential health dangers of mountain climbing in high altitudes and deep-sea diving. They write a health and safety column for a fictional magazine about extreme outdoor sports that explains the risks involved in...

In this vocabulary instructional activity, students match a given vocabulary word to the correct definition.  Words include such terms as altitude, centroid, circumcenter, circumscribed circle, inscribed circle, median and...

In this classifying triangles worksheet, 10th graders solve and complete 11 different types of problems. First, they state whether each segment shown is an altitude, median, or neither. Then, students solve for x and find the requested...

For this graphing trigonometric functions worksheet, 11th graders solve and complete 10 various types of problems. First, they graph each functions as shown. Then, students find the domain in each given function. In addition, they find...

In this triangles worksheet, 10th graders solve and complete 2 different problems. First, they find the perimeter of each triangle as described. Then, students find the slope of each side and altitude to each side of the triangles. In...

In this parts of similar triangles worksheet, 10th graders solve 6 different problems related to determining the value of various parts of similar triangles. First, they find the value of x in the 2 figures shown. Then, students find the...

In this special right triangles instructional activity, 10th graders solve 9 different problems related to measuring various types of right triangles. First, they find the values of x and y in each right triangle shown. Then, students...

Students use a ruler to determine length and then fit the unit to a scale in miles. This unit will also give a geological awareness of altitude and the difference it makes in travel time. The travel time with Mapquest will obviously be...
