Eighth graders measure the circumference and the diameter of circular objects and record the measured values of the circumference and the diameter in a table. They then record their measurements in centimeters and use their data to...

Students define slope, and practice finding the slope of lines through given points. They determine the angle of inclination. Students find the relationship between the slope and the tangent of the lines. Students determine special...

Students identify the relationship between chords, secants and circles. For this geometry lesson, students calculate the length of the chords. They sketch the secant lines on a circle.

Learners solve problems by finding the radius or diameter. In this geometry lesson, students identify the tangent line of a circle and use properties of circles to find the radius. They relate circles to the real world.

In this calculus worksheet, students calculate the relationship between a line of tangency and a secant side length. They are given the formulas to solve their problems. There are 9 problems.

In this math worksheet students use the intermediate value theorem to solve two problems. They find parallel lines that will cut a convex shape into two pieces with equal areas. Students repeat this problem with a concave shape. Students...

First graders analyze characteristics of geometric shapes. They identify, describe, and create simple geometric figures. They analyze characteristics of geometric shapes and determine the defining attributes of a circle,...

Geometry could be called the study of figures. An overview of the figures found in a typical geometry course contains a study of different triangles, quadrilaterals, and regular polygons. 

Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...

A daily counting routine builds a caterpillar with 100 body segments (marked with symbols to indicate 2s, 5s, and 10s) by the 100th day of school. Provides structured repetition as part of the morning routine so that by 100th day,...

Students examine and study how to recognize the characteristics of a regular pentagon and demonstrate how to construct one. They become aware of associating a regular pentagon to its term of a double map and practice the concept of line...

In this consonant blends worksheet, students find the correct word for each picture using the words in the box. Students then write the word on the line and circle the consonant blend.

In this problem solving learning exercise, high schoolers answer 10 multiple choice SAT practice problems.  Students find the area of circles, slope of a line, solve absolute value inequalities, etc.

Your geometry learners will discover and show the construction of the circumcenter of a triangle. Guided by the steps in the activity, they construct perpendicular bisectors of each side that have a point of concurrency called the...

Acute angles, nets, and vertices are only a few terms that a set of flash cards includes. Among the 108 cards, two types are available; word cards printed in bold-faced lettering, and corresponding definition cards equipped with an...

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

You've investigated relationships between chords, radii, and diameters—now it's time for arcs. Learners investigate relationships between arcs and chords. Learners then prove that congruent chords have congruent arcs, congruent arcs have...

Eighth graders explore the characteristics of a circle and the formulas to find circumference. They use a bicycle wheel to determine the circumference around a wheel. They utilize a worksheet imbedded in this plan which has a variety of...

Students follow detailed directions to use the GeoGebra program. In this mathematics instructional activity, students find the nth term of a sequence, and use line art to approximate a Bezier's curve. Students locate points and segments...

Does having an addict in your family make it more likely to become one yourself? Explore the genetic risk factors, as well as the prominent environmental influences, for substance addiction in a lesson that encourages awareness and open...

In this patterns worksheet, 4th graders look at 2 solids, a cone and a cube, and then circle the multiple choice letter of the net for each solid.

Students relate the ratio of Pi to the diameter of a circle. For this geometry lesson, students investigate the relationship of the chord of the circle the the number Pi. They define ration, chord, circumference and diameter and find...

For this geometry worksheet, 10th graders use a straightedge and a compass to construct congruent segments and angles, bisect a segment and an angle, construct perpendicular and parallel lines, construct tangents, circumscribe a circle...

Learners calculate the inscribed angle of a triangle. In this geometry lesson plan, students identify the angle created by intersection of a triangle and a circle. They see the relationship between the arc and the angle.
