In this geometry worksheet, 10th graders use the midpoint formula to calculate the midpoint of a line segment given a pair of coordinates. There are 8 questions with an answer key.

In this geometry worksheet, 10th graders determine if a given segment is a median or altitude of a triangle and use then find the indicated missing length or equation of a line.  The two page worksheet contains twenty...

In this geometry learning exercise, 10th graders identify the vocabulary associated with the Triangle Midsegment Theorem and solve problems in which they find the size of a missing angle or segment.  The one page learning exercise...

In this geometry worksheet, 10th graders review the vocabulary associated with the special segments of a triangle and the associated points of concurrency and solve problems in which they find the indicated missing angle or...

Sixth graders brainstorm the ways a person's actions can affect a community. As a class, one classmate is given a ball of yarn and pass it along to another student creating a web. Next, some classmates are asked to drop their part and...

Solving systems of equations underpins much of advanced algebra, especially linear algebra. Developing an intuition for the kinds and descriptions of solutions is key for success in those later courses. This intuition is exactly what...

In this equation of an ellipse worksheet, students find the missing numbers in 8 equations when given the drawing of the ellipse. Students graph 9 ellipses on a coordinate grid when given the equation. In the final activity, students...

Seventh graders identify the use of a function.They are asked to describe the input and output of a function. Students also identify different aspects of the coordinate system and represent functions in a visual graph.

In this segments and rays learning exercise, students sketch relationships, find the missing measurements, and find coordinates of the midpoint of segments on a number line.

In this proportion worksheet, students use proportions to find the missing side of similar triangles, they identify the percent of a number, and graph points on a coordinate plane. Students solve real life story problems dealing with...

In this geometry worksheet, 9th graders classify quadrilaterals by using coordinate geometry and the properties of various quadrilaterals. The seven page worksheet contains eleven questions. Answers are...

Young scholars investigate and solve Pythagorean triples. In this geometry instructional activity, students find the missing sides and angles of a right triangle. They graph right triangles and move the sides around to create different...

Students investigate the Pythagorean triples. In this geometry lesson, students solve for different parts of a right triangle. They identify the missing side or angle using the pythagorean theorem.

Students solve for missing sides using the Pythagorean theorem. In this algebra lesson plan, students derive the six trigonometric values using the right triangle. They relate the Pythagorean theorem to the distance formula.

Students calculate the different ratios using a right triangle. In this trigonometry lesson plan, students identify the sine, cosine and tangent of each side. They find the missing angles using the different ratios.

In this algebra worksheet, students spell out the name of the integer and count the number of letters. This number becomes the y value for the graph. After solving for the missing y-value, students plot their coordinate pairs.

Students solve and verify the solution for unknown measures. In this geometry lesson, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

In this online interactive grammar skills worksheet, students examine 10 sentences that are missing words and select the appropriate words to complete each of the sentences and match them to the sentences. Student answers are scored...

Students find missing angles and sides of triangles. For this geometry lesson, students create intersecting lines to measure angles. They use Cabri Software to create virtual angles.
