Students investigate the relationship between perpendicular and parallel lines on a coordinate plane. In this geometry activity, students differentiate lines based on their slopes.

In this math worksheet, students will work independently to trace a stencil on an x-axis. Then students will follow a procedure to trace the image on the horizontal line of reflection. Students will observe that reflections and rotations...

Explore plants and flowers with this lesson. Learners talk about plants, conduct an experiment with suflowers, and track a plants growth. This is a motivating way to present this concept.

Second graders investigate how to slow the spread of germs from coughing and sneezing. In this illness prevention lesson, 2nd graders talk about why people cough and sneeze before telling about ways to prevent the spread of germs. They...

Students measure and calculate the angle of the sun. They compare the leaf types on the north and south to compare the effects of the sun on the type of vegetation. They complete the activities inside the classroom or on a trip to a...

Students explore how to select among choices of variables and analyze the cost-benefit ratio of their short and long term planning in a team activity as they consider the planning and operation of a ski slope.

Students identify angles.  In this angles that pair lesson, students identify adjacent, vertical, complementary, and supplementary angles.  They use straws, pretzel sticks to demonstrate given types of angles. 

Eighth graders find missing angles of triangles, quadrilaterals and angles formed by parallel lines cut by a transversal. They use area formulas to find the area of a figure; find the complement and supplement of a given angle; and know...

Students determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and theorems.

Students watch teacher demonstration of distance formula, view non-collinear cities on maps, plot points on coordinate plane, evaluate square roots, compute distance between two points, and use Heron's formula to find area of triangles.

Students test the adhesive strength of different tapes. In this adhesive lesson, students conduct an experiment to test the shear strength of the adhesives, take measurements, record data, and draw conclusions to explain each product's...

In this geometry worksheet, 10th graders identify the missing angles using the polygons sum conjecture. They measure exterior and interior angles using their angle theorems. There are 63 problems.

Learners 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.

Sixth graders investigate the nutritional value of different types of cereal. They take a survey of students that ate breakfast and create a circle graph with the results. Students examine the nutritional information on the sides of the...

Students explore the concept of boomerangs. In this boomerang lesson, students throw homemade boomerangs at different angles to record maximum distance and if it returned or not. Students collect their boomerang data then create a...

Students conduct an experiment and use different measurements of a single root to illustrate the mechanism of plant movement.

Students are introduced to Kepler's 2nd law of Planetary Motion. The lesson reinforces the understanding of focal points. They calculate the sector area of an ellipse.Students expand understanding by modeling Kepler's 2nd Law of...

Students conduct an experiment to determine if a plant's response to gravity is affected by different angles of plant orientation.

Young scholars conduct an experiment to determine how the absence of a root cap affects a plant's ability to sense gravity. They make comparisons between capped and decapped roots.

Learners investigate the connection that exists between Algebra and Geometry. They classify two and three-dimensional figures. Pupils use formulas to solve problems in geometry and use appropriate measuring devices in the right contexts.

Ninth graders operate a model to observe the type of motion that occurs at a fault during an earthquake. They explore the effects of several variables. Students measure movement, calculate averages and plot and graph information.

Students derive the six trigonometric identities. For this trigonometry lesson, students review the parts of a right triangle and use the Pythagorean theorem as a guide to find the trig identities. They find sine, cosine and tangent ratios.

Learners discover soil and Earth movement by experimenting in class.  In this Earth Science lesson plan, students utilize a stream table, soil, graduated cylinder and water to create a re-enactment of a landslide.  Learners...

Fifth graders engage in a variety of hands-on and technology-rich activities involving the classification of quadrilaterals. They utilize protractors and rulers to investigate the characteristics of various types of quadrilaterals. They...
