Challenge your class to construct a definition for trapezoids. Looking at four examples and four non-examples, students individually create definitions and use them to classify an unknown shape. Allow for small group and whole-class...

Sixth graders examine the Lewis and Clark Expedition. In this plant discovery lesson, 6th graders put in chronological order the plant discoveries of Lewis and Clark. Students understand the characteristics of leaves and find the area of...

From a circle to a cycle! The final lesson of a five-part series challenges learners to use points from the unit circle to plot a repeating pattern. The repeating patterns become the graphs of the trigonometric functions. Scholars...

So many times the characteristics of triangles are presented as a vocabulary-type of lesson, but in this activity they are key to unraveling a proof. A unique attack on proving that an inscribed angle that subtends a diameter must be a...

Young scholars classify and compare plants using specific information, observations, and numbers. In this mathematical inquiry lesson, students use plant characteristics to describe, compare, and classify them. They attempt to develop a...

Build a solid foundation on which to develop future concepts. Through a guided exploration, learners compare and contrast the characteristics of points, lines, planes, rays, and segments. They measure lengths and practice notation for...

How long does it take alcohol to leave your system? Individuals explore this question by examining a polynomial function. They draw conclusions by analyzing the key features of the given polynomial function.

Examine statistical data that shows an overlap in responses. The data tallies over 100% and learners interpret this data characteristic. They then create a graph to represent the data.

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Learners use the sum angle formula for sine to derive the sum and difference formulas for cosine and tangent. The level of difficulty is quite high. Learners must be familiar with trigonometric identities as well as the characteristics...

Alegebra amateurs identify the slope and the y-intercept given a linear equation in slope-intercept form by correctly completing some in class problems. They write the linear equation in slope-intercept form that corresponds to the given...

Students will define circle and radius. In this radius lesson,  students are given a circumference, they will write an equation and sketch the circle. Students will match graphs of circles to their equations.   

Fifth graders explore plant characteristics by viewing a flower and seed presentation. For this environmental adaptation lesson, 5th graders identify specific traits plants have in order to allow them to grow in different climates...

High school and college learners identify forestry career opportunities. They identify the parts of a tree cross-section and trees based on their leaves and characteristics. Pupils calculate board feet and explain safe methods of...

Written as an accompaniment to a field trip to the Out of Africa Wildlife Park in Arizona, this is an interdisciplinary, themed instructional activity on lions. Even if you cannot take your upper-elementary kids to this attraction, there...

Students study pictures of seeds and the conditions in which they grow during their study of archaeobotany. They infer ancient plant use by looking at archaeobotanical samples. They determine the change of plant use by interpreting a...

In this geometry worksheet, students explore graphing characteristics. Students complete seven short answer and problem solving questions about graphing and whether or not one can be traced.

Middle schoolers measure and record their height in centimeters on a graph. By integrating math and science, students collect data and apply graphing skills to the experiences they are having growing plants. Finally, middle schoolers...

Students harvest and thresh the seeds. They count the seeds and compare that number with the original number of seeds planted (8) to determine their profit or loss. Finally, students think about additional questions they have about...

Fourth graders use math software and geoboard paper to design basic shapes. They write individual definitions for the geometric shapes based on what they see in the shapes. They apply their background knowledge of the shape as they write...

Fifth graders are introduced to the topic of means. Calculating the mean, mode and median, they describe what each set of numbers tell and do not tell about the data. They use a line graph to practice finding the mean. They also use...

Seventh graders explore the Eastern Hemisphere. They investigate the customs, currency, climate, location and other facts needed in order to travel to a specific country. Students receive a stamp on their "passport" when their research...

Students solve problems. In this math lesson, students write solutions using LOGO commands in order to help get the turtle to the pond.

Based off of the hit television show NUMB3RS, this lesson introduces students to the concept of Multi-Attribute Compositional Models, in which market experts determine what features are most in demand for a given product. The lesson is...
