Students read the article Blood Test Predicts When You'll Die. For this reading comprehension lesson, students read the article and complete a variety of activities. They work individually and in pairs to complete questions dealing with...

Young scholars use similar triangles and a sight tool to find the height and distance between large objects. In this similar triangles lesson plan, students use a constructed sight tool to measure the distance and height of an object...

Twelfth graders define an arc and find its length. In this calculus lesson, 12th graders roll out a circle and measure its length using the same method of a triangle and its hypotenuse. They apply the Pythagorean Theorem to some...

In this composite figures worksheet, high schoolers solve 11 short answer problems. Students find the area of figures composed of various polygons. High schoolers find the area of each figure given a sketch of the figure with various...

Young scholars explore momentum. In this physics lesson, students perform an experiment in which two balls are released on slanted boards while young scholars observe which ball will go the farthest and the fastest. Students define and...

Learners explore characteristics of mass. In this scientific inquiry about mass lesson, students drop rocks of different weights from various heights and record the depth of the "crater" created.  Learners record their findings on a...

In this similar figures worksheet, students use proportions to solve 6 short answer and multiple choice questions.  Students use proportions to answer questions about map scales and height of trees given shadow lengths.

Sixth graders experiment with an atlatl and dart.  In this sixth grade data management mathematics lesson, 6th graders explore and determine the most suitable methods of displaying data collected from their experimentation with...

Sixth graders explore standard and nonstandard measurement. In this measurement lesson, 6th graders estimate the lengths of different objects and write about their observations during measuring. Students work in groups to...

Students view a quicktime video of basketball players going from Atlanta to Springfield, Mass. In this scaling lesson, students use a map to calculate the distance of the trip and the length of travel time. Students apply ratio and...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

How many different types of triangles can your class name? A discovery lesson guides learners through an exploration of the different triangle types and the relationships between their angles and sides. Using coordinate geometry,...

Estimate the value of one of the most famous irrational numbers. The hands-on instructional activity instructs classmates to measure the circumference and diameters of circles using yarn. The ratio of these quantities defines pi.

What can shadows tell us about the changing season? Over several months, astronomy learners record length and position of an outdoor object's shadow, such as a flagpole. They apply the data to a growing hypothesis and note the...

You've heard that it is true, but can you prove it? Scholars learn the Pythagorean Theorem through proof. After an overview of proofs of the theorem, learners apply it to prove triangles are right and to problem solve. This is the second...

Young mathematicians collect data on the arm spans of classmates. Then they sort the data by measures of center, spread, and standard deviation. Finally, they compare groups, such as boys and girls, to interpret any differences. 

Potty humor is always a big hit with the school-age crowd, and potty algebra takes this topic to a whole new level. Here the class develops a model that connects the dimensions (radii, paper thickness, and length of paper) of a...

Does doubling mean everything doubles? Learners adjust the scale factor between two rectangles. Using the calculated measurements, pupils investigate the ratios between the lengths, perimeters, and areas of the rectangles.

Make sure the measurement is right. The interactive provides right triangles with a missing side measurement. Pupils use the given sides and the Pythagorean Theorem to calculate the length of the missing side. After entering the length,...

If driving to school only takes 10 minutes, then how long does it take to drive to a tropical rainforest in Colombia? Explore the focus question in a lesson that uses measurement tools and formulas to figure out the time and...

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

Investigate relationships between angles, arcs, and segments in circles. Pupils use geometry software to discover the relationships between angles, arcs, and segments associated with circles. Class members use similar triangles to...

Bring math and reading informational text together with a reading comprehension lesson. After kids read about isosceles, scalene, and equilateral triangles, they answer five comprehension questions to demonstrate how they can use context...
