Students research characteristics of different body parts. Students design and sketch a prosthetic they developed. They share their idea with the class and complete a worksheet.

Students discuss the sum of central angles and use string to create them on circles. They find the measure and length of both minor and major arcs. Students give examples of concentric, similar, and congruent circles and congruent arcs.

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 practice identifying fractional parts represented in pictures and phrases. In this fraction lesson, students determine the proportion represented by common time and money phrases such as "3 hours in a day". Students match their...

Students explore primary and secondary colors. In this lesson on light and color, students complete four different activities which include mixing colors, creating secondary colors from primary colors and observing the colors in a bubble.

Ninth graders explore vectors.  In this vectors lesson students complete a lab activity. 

Students experiment with mirrors to explore the Laws of Reflection.  In this experimental lesson students develop their own experiments and follow a list of assigned steps then report what happens in their activity. 

Students examine quadrilaterals including properties, definitions, and names.  In this quadrilateral lesson students apply the correct property to the different kinds of quadrilateral. 

Students identify the special segments of triangles, the median, angle bisector, altitude, and perpendicular bisectors.

Learners are introduced to the relationship between light and vision. In groups, they participate in experiments to discover how different wavelengths are divided in the visible spectrum. They record their answers and discuss their...

Students discover three lettered postulates that prove triangles congruent.

Fifth graders compare the relationship between meter in music and measurement in math. They practice sightreading music by determining the number of beats per measure, clapping and counting the rhythm.

Eighth graders create rockets that be launched at varying angles to determine which angle is best to launch at for the longest distance.

Students identify different geometric shapes, and arrange them artistically in original jewelry designs.

Middle schoolers estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays

Students explore the concept of angles by interacting with numerous types of measurements. They create index cards with different angles. Then they pass the cards around to other students for comparison and measurement. They practice the...

Fifth graders work with polygons.

Fourth graders, in groups, locate, comprehend, interpret, and evaluate information about celestial bodies that influence ocean tides on Earth. They apply this information through graphic representations.

In this geometry worksheet, students answer questions about midpoints, distance, lines and segments. They are given different shapes and asked to calculate the angles, and sides of polygons.

Second graders measure and grid their ideas for the new classroom floor plan. They create their own ideas for the classroom arrangement on grid paper. When they finish, they share their draft plan with their peers and with the teacher...

In this shapes and designs worksheet, 10th graders solve and complete 6 different types of problems. First, they fill in the first two columns of the table show with their shapes. Then, students measure the interior angles of each...

Students construct models of various tricubes, tetracubes, and pentacubes that are possible, classify n-cubes into different groupings, and draw these figures on isometric dot paper giving true perspective to what they visualize.

Students examine estuaries in Delaware. They, in groups, gather samples of water to find organisms and identify them.

Students analyze inscribed angles and intercepted arcs and explore the relationships between the two. They investigate the properties of angles, arcs, chords, tangents, and secants to solve problems involving circles.
