Students receive a copy of a "Spaghetti Measure" task sheet along with the scoring rubric. Students preview the task and the rubric prior to starting the task. tudeThey determine the circumference of a circle of spaghetti that will...

Students calcute distances using trigonometry and angle measurements. They estimate the width of the Trig River, measure it and compare their results with their classmates. They collaborate with a group to research and find the results.

Students discover the Pythagorean Theorem.  In this discovering the Pythagorean Theorem instructional activity, students measure the lengths of various triangles to the nearest centimeter. Students record their measurements in a...

In this trig functions worksheet, students find the trig values of 46 problems.  Students find the trig values of various radian measures.  Students use trig properties to prove trig identities.

Young scholars create a project applying their math skills as they discuss energy conservation. In this geometry lesson, students define vocabulary relating to the environment and energy conservation. They construct a building that allow...

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...

Learners use the axes and measure angle tool to explore and calculate complementary angles with Cabri Jr. They also identify what happens to the calculation as they drag the endpoint into a different quadrant. Finally, they label each...

Fifth graders use the SMART Board to demonstrate how to use a protractor to measure acute, obtuse, and right angles. In this protractor lesson plan, 5th graders also complete an angles worksheet.

Students are introduced to some basic concepts of geometry. They explain that the definition of a triangle is a figure with three sides, three angles, and three points. Triangles can be named by using three points in their correct sequence.

Young scholars explore geometry by using computer applications. In this spatial measurement lesson, students discuss the difference between area, weight, volume and other forms of measurement. Young scholars utilize computer applications...

Students discover the relationship between the sides of a polygon and the number of diagonals that can be drawn from one vertex, the number of triangles that those diagonals form, and the sum of the interior angles of that polygon.

Students discover how to use various tools to measure and draw angles. With protractors, they classify angles according to angle measure, identify vertical angles, and perform angle additions. For their final project, students create...

What do you do when you don't think you have enough information? You look for another way to do the problem! Pupils combine what they know about finding the area of a triangle and trigonometry to determine triangle area when they don't...

A basic set-up leads to a surprisingly complex analysis in this variation on the question of surrounding a central circle with a ring of touching circles. Useful for putting trigonometric functions in a physical context, as well as...

Students draw diagrams demonstrating how it is possible to two central angles to be congruent and their minor arcs are not congruent. In groups, they illustrate theorems with their constructed circles, create diameters of circles that...

Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.

Students use the human body as a foundation for gaining practice in measuring angles and calculating ratios and proportions.

Learners draw triangles on their graphing calculators using the Cabri Junior application. For this graphing calculator lesson, students follow step by step directions to create triangles on their calculator. They identify the type of...

Young scholars, just like Eratosthenes, try to use math to calculate immeasurable objects. Teachers need to try out the calculations before having your class do them. They should take notes to be included with their own calculations and...

Students construct and test balloon rockets and a model rocket. For this rocket science lesson, students use an inquiry-based method to master balloon rockets and have a shoot-off with the goal of attaining the highest altitude. Next,...

Learners identify a right angle and right triangle. They perform WebQuests searching for similar figures and solve for the length of one of the sides given the other two.

Students measure objects effectively using standard units, They examine how consistency in the units used allows for easier and more accurate communication of mass measures.

Students engage in a instructional activity that is concerned with the concept of quadrilaterals and how they are used to create a rectangle for a door. They create a drawing of a quadrilateral while finding the sum of the angles. They...

Students identify how tall a tree is. In this measurement lesson plan, students use "luminometers" to measure a tree and complete a data sheet.
