This unit on connecting algebra and geometry covers a number of topics including worksheets on the distance formula, finding the perimeter and area of polynomials, the slope formula, parallel and perpendicular lines, parallelograms,...

Graph equations of lines using the slope-intercept method or by plotting both x and y intercepts. Determine if two lines are parallel or perpendicular by comparing their slopes. This handout includes step-by-step directions and four...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Learners investigate the side splitter theorem. In this geometry lesson, students estimate and solve problems dealing with ratios and proportions. They identify angles created by lines that are parallel.

Where do the coordinates lead? As children brainstorm ways to find the location of different buildings, they learn about coordinate points and how to use them to locate areas on a grid or map. They practice using ordered pairs by playing...

Discover the results of reflecting an image. Learners use transparency paper to manipulate an image using a reflection in this fourth activity of 18. They finish by reflecting various images across both vertical and horizontal lines.

Starting with a paragraph of information presenting the different ways we can observe planetary objects, pupils work through these instructions to see how they can observe and measure angles.  Your class will discover how these...

How do you prepare class members for the analytical thinking they will need in the real world? An assessment requires the higher order thinking they need to be successful. The module focuses on the concept of rigid transformations...

By looking at the direction of the parallel streets of New York and figuring which days the setting sun is directly visible along those lines, your class can calculate the degree and angle of the sun. A really nice lesson, giving a...

A set of 49 math vocabulary cards ranges from angle to irregular polygon to parallel lines. Each sheet contains two cards: one with the word printed in bold text and the other with the definition.

Tenth graders explore mathematics by participating in hands-on daily activities. Learners identify a list of different shapes and classify them by shape, size, sides and vertices. They utilize tangrams and geometric pieces to gain...

Sixth graders explore different geographic relationships in like drawing lines, rays, and parallelograms. This lesson could be used for review because it covers more than one concept. The students should have prior knowledge.

Second graders gather and graph data.  In this graphing lesson, 2nd graders collect data and graph this information using tally charts, bar graphs, pictographs, or tables. They make predictions about the outcomes.

Students walk around the neighborhood and identify various polygons and lines in buildings, nature and other objects. They design a building using various geometric patterns, shapes and lines. Students complete a descriptive writing of...

Investigate geometric reflections in this geometry lesson. Create geometric reflections that show the reflection across the x and y axis of a coordinate graph. Learners watch a teacher demonstration before proceeding on their own. They...

Students analyze midsegments of triangles in this lesson. They use Cabri Jr. software to observe the relationships between interior angles and midsegments of triangles. Specific instructions for creating this lesson in Cabri Jr. are...

Rigid motions are to congruence as what are to similarity? Investigate properties of rigid motions and define congruence in terms of rigid motions with the ninth chapter of a 10-part eighth grade workbook series. The...

Students look at the geometry in an artwork. In this art history/geometry instructional activity, students research the artist Charles Sheeler and look at his painting Stacks in Celebration. They find the different types of lines,...

In this algebra and geometry worksheet, students review concepts dealing with angles, lines and basic word problems. They practice answering questions similar to the ones on the SAT.

Learners are posted at the beginning and end of a 10-meter long line parallel to the ocean and are instructed to look straight ahead towards the water. The student at the beginning of the line uses a stopwatch, goes to the water's edge...

Students learn and review basic geometric terms, definitions, and theory, including regular polygons, lines, angles, points, etc. They make a tessellating stamp and create a repeating work of art.

Students explore the global grid system. In this globe instructional activity, students identify latitude and longitude lines and how these can tell the coordinates of any place. They use the Internet to find the exact coordinates for...

In this geometry instructional activity, 10th graders practice taking math questions that are on the SAT. The questions deal with a variety of different math. There are 10 questions with an answer key.

Bring out the inner artist with this Abraham Lincoln lesson plan. Elementary students work on a home project creating a hat similar to Abraham Lincoln's hat. They will use geometry and measurement to create the scale of the hat, then...
