Pupils discover how to recognize tangents and how to use their properties. They investigate and use the properties of angles, arcs, chords, tangents, and secants. Students use two tangents and the properties of similar triangles to...

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.

Third graders describe an amount of turn from a particular position to another using the 'circular' benchmarks of 0, ++, ++, ++, and full turn. Estimation language such as 'just about', 'between', 'not quite', 'just over', and similar...

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.

Fifth graders describe and demonstrate how trigonometry can be used to find the height of a tall building or tree. They describe and demonstrate how trigonometry can be used to find the height of a high hill, or other high object where...

Second graders be having hands-on experiences with three-dimensional solid shapes. They investigate the features of solid shapes and examine the names for them. They are introduced to making nets for 3D shapes.

Fourth graders work in co-operative teams of four to complete a puzzle. Each student initially works independently, and then the team jointly puts together the four shapes they have individually made, to complete the puzzle.

For this parts of a circle worksheet, students correctly identify labeled parts of circles, choosing from diameter, chord, radius or center. A reference web site is given for additional activities.

In this circles worksheet, students complete multiple choice questions, determining whether diameter, radius, chord or center is shown on a circle. A reference web site is given for additional activities.

In this parts of a circle worksheet, students check the correct answer, describing the labeled part of a circle as either diameter, chord, radius or center.

In this missing line length and missing angles worksheet, students find measures of missing angles and find missing lengths. A reference web site is given for additional activities.

Students explore lines, rays, line segments, and planes. In this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Students collaborate in graphing additional functions.

Students identify diagrams of quadrilaterals and circles by different names and classify the figures. They name the areas for each diagram and practice solving the formulas for each.

In this measurement lesson, learners examine the Pythagorean Theorem, perimeter, and areas of right triangles. They record their measurements and research their findings on a grid.

Students practice using a protractor and ruler to draw various points and lines. Using a computer, they draw the points and lines in the program and describe the differences between their drawing and the computer's drawing. They complete...

Learners explore the concept of polygons on a two-dimensional plane. They identify polygons in everyday life and draw different polygons according to their classification. Using a geoboard and geobands, they consrtuct polygons and even...

Students calculate the square root of a given number using carpenter's square measurements. In this math lesson, students relate this method on the Pythagorean theorem. They answer practice problems after the exploration activity,

Pupils describe geometric figures. They create pictures and list each shape they used to create their pictures. They discuss the importance of shapes in their lives and create ten different geometric shapes using the Drawing tools in...

Students listen carefully and put pieces together following the teacher's instructions. They point to the different shapes and sizes as they are being called out and count the number of items they have in front of them. They decorate...

Students create a pyramid design based on the 6 simple machines that they are introduced to. In this simple machines lesson plan, students are introduced to the wedge, wheel and axle, inclined plane, screw, and pulley.

Youngsters recognize and identify shapes. They draw, and use modeling clay to make shapes. They also identify shapes in their environment and in the Navajo culture, then compare the shapes and sort them into groups. This is the...

Young mathematicians classify squares according to attributes. They sort squares according to specific attributes. Learners explore squares in repeating patterns and order squares according to size. Engaging extension activities are...

Identify the length, width, and height of prisms. Critical thinkers calculate the volume of prisms given small amounts of information. They derive the formula given the length, width and height.

Ready to introduce your class to the coordinate plane? This website includes a detailed lesson plan that includes two interactive games to help learners practice graphing ordered pairs. The scripted discussion is a little cheesy and a...
