In this intersecting lines worksheet, 10th graders identify and complete 10 different problems that include equidistant intersecting lines. First, they write the equation of the locus of points equidistant from the x-axis and the y-axis...

Students measure angles that are formed by parallel lines and a transversal lines. In this angles lesson plan, students measure and define angles that are made by parallel and transversal lines. They will color code the angles based on...

Students solve systems of equations with fluency. In this algebra lesson, students graph, use elimination and substitution to solve systems of equations. They identify the point of intersection using algebra.

Students solve systems of equations. In this algebra instructional activity, students identify the domain and range of each function. They use the slope and y-intercept to graph each line.

Learners explore intersecting lines. In this intersecting lines lesson, students investigate shapes consisting of parallel, perpendicular, and similar lines. Learners investigate these lines in shapes around them.

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...

Earth scientists answer five multiple choice questions about the topographical map atop the worksheet. Use this as a quick assessment of understanding after having taught how to read contour lines and topographic maps. 

Lead your high school class on a journey through the world of symmetry and reflections as you discuss geometric principles. Pupils differentiate between reflections and rotations, explore rotational symmetry, and investigate how to...

The shortest distance between two points is a straight line. Learners use the Pythagorean Theorem to develop a formula to find that distance. They then find the midpoint using an average formula. 

This is an interesting geometry problem. Given the figure, find the area of a triangle that is created by the intersecting lines. The solution requires one to use what he/she knows about coordinate geometry, as well as triangle...

Demonstrate the meaning of an absolute inequality using three different methods. Here, scholars explore absolute value inequalities through graphing, number line distance, and compound inequalities. Pupils complete various activities to...

Flip the script! Reverse the situation and ask the class to find the function given asymptotes. The task requires class members to use their knowledge of functions and asymptotes to create functions that have a given asymptote or...

Students perform reflections and translations of polygons. In this geometry lesson, students perform reflection in two parallel lines. They use Cabri to observe the transformation and rotations of each shape.

In this angles and parallel lines worksheet, students solve 40 problems that pertain to parallel lines, supplementary, vertical, corresponding and alternate angles. There is instruction on the page with examples. This page is intended as...

In this algebra activity, students factor systems of equations using elimination and substitution. THey graph their lines and find the point of intersection. There are 15 questions.

Horses need exercise, too. Scholars create linear equations to model the perimeter of exercise fields for horses. They finish by solving their equations for the length and width of the fields.

Come full circle in learning about conic sections. Learners first look at the type of conic section formed when concentric circles intersect a standard coordinate plane. They then see which type forms when two sets of concentric circles...

Scholars learn how to find the distance of vertical and horizontal line segments on the coordinate plane in the 19th installment of a 21-part module. The use of absolute value comes in handy.

Beginning physics scholars interpret two graphs depicting position versus time. For each graph, there is a series of questions to answer. The exercise is basic, but beneficial. Consider using it as an assessment of understanding after...

A lesson involving mapping, the use of a compass, writing and following directions, and exploring the first two themes of geography is here for you. Learners create original maps that show the routes they take through their own...

Review context clues with your young readers using this helpful resource. Eight questions contain a missing word that pupils choose out of five options. The sentences provide ample context clues, making the choice more about test-taking...

Introduce pupils to the two types of reasoning, inductive and deductive. Classmates work in pairs or small groups to learn the difference between the two and apply these reasonings to develop valid conclusions. 

In this pentagram worksheet, students examine a pentagram and number the intersection of lines.  They number the crosspoints in such a way that the sum of the numbers on each line are equal.  This one-page worksheet contains 1...

Students find the orthocenter of a triangle. In this geometry activity, students identify where the altitudes meet in a triangle. They use Cabri software to explore acute, obtuse and right triangles.
