Coordinate Geometry Teacher Resources

Don't be a square! Young mathematicians determine the slope and length of a line segment. They then prove whether four given coordinate points form a square.

Translating complex numbers is as simple as adding 1, 2, 3. In the ninth lesson plan in a 32-part series, the class takes a deeper look at the geometric effect of adding and subtracting complex numbers. The resource leads pupils into...

Students use Cartesian coordinates to plot current natural disasters. They relate location of natural disasters to their specific major project countries. Students tie in geometry within this lesson plan as connected to spatial...

You'll be spinning in unit circles once you read through this jumbo-sized resource of everything you need to know about trigonometry. Each page has color-coded examples with explicit directions that detail the problems and formulas. 

Students investigate the ties that architecture and math have in common. They focus on works of architecture in the world that is considered of great significance. Students use the internet to find building images from around the world....

Students use Cartesian coordinates or degrees of latitude and longitude to locate important locations within their specific countries. They Use a grid to apply the concept of latitude and longitude, or positive and negative Cartesian...

Students find coordinate points on a grid and create a line graph with those points. This lesson should ideally be used during a unit on various types of graphs. They make and use coordinate systems to specify locations and to describe...

Students identify different properties of parallelograms. In this geometry instructional activity, students complete problems that proves the theorems and properties of parallelograms. They graph the different shapes on paper.

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

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

Young scholars differentiate between ellipse and hyperbola. In this algebra lesson, students graph and solve elliptical equations. They use the cabri program to create the different conics and move them around.

Students investigate the relationship between angles of triangles. In this geometry instructional activity, students identify properties of right and non-right triangles. They differentiate between vertical and supplementary angles.

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

Pupils investigate symmetry in the real world. In this geometry lesson, students inter-relate math and technology. They create and name a variety of polygons.

Students relate the ratio of Pi to the diameter of a circle. In 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...

Learners investigate circles and compound locus. In this geometry instructional activity, students identify the distance from a point to a line. They use Cabri software to create lines and circles.

Tenth graders change numbers written in standard form to scientific notation. In this scientific notation lesson, 10th graders use given diameters and distances from the sun for each planet in our solar system. After rewriting each of...

Students investigate the movements of the planet Pluto. Students participate in a hands-on activity to record data similar to the movements of the planet Pluto. Students compare their data to that found on a website.

Young scholars explore how GPS works, the mathematics behind the technology, and how GPS is used. They find positions in one and two dimensions, and participate in a WebQuest that explores how math is used to find a location on Earth...
