Coordinate Geometry
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...

Distance on the Coordinate Plane
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.

Treasure Hunt: Coordinate Graphing
Two of the best words any one can hear– treasure hunt! Your class will be excited to practice graphing on a coordinate grraph as they identify and write coordinates for landmarks they see on a treasure map. They trace their route to the...

How Do Cartographers Find Points on a Map?
Ninth graders describe latitude and longitude and how they may be useful to find things on a map. In this cartography lesson students divide into groups and devise a coordinate system that can be used to communicate a position.

Coordinate Graphs
Students use coordinate graphs in order to identify objects and their locations. They are shown how to plot the x and y coordinates and then are given values to be plotted during guided and independent practice. Students are assessed on...
Curated OER
MAP MAGNETIC FIELD OF A ROOM
Students map the magnetic field of a room (classroom or room at home -- recommend kitchen) at two or more heights. They create a coordinate grid within the room and make a relatively accurate map of the room to super impose the...

Identify and Graph Linear Equations
Students investigate linear functions. In this mathematics lesson, students plot points onto a graph by solving the equations y=x and y=mx+b by being given numbers for x and solving for y.

Grids
Take your study of coordinates online! Groups of students complete an online graphing introduction, plotting the points of virtual objects. A worksheet is included for extra practice.

Goldilocks and the Coordinate Grids
Where this lesson idea is lacking in materials, it makes up for with creativity! Using "Goldilocks and the Three Bears" as the background, mathematicians plot points on a coordinate grid to create props for the story. The polygons all...
Mathematics Assessment Project
Representing Inequalities Graphically
A new, improved version of the game Battleship? Learners graph linear inequalities on the coordinate plane, then participate in a game where they have to guess coordinate points based on the solution to a system of linear...
Curated OER
Word Webs And Mind Maps
Students develop a simple understanding of the brain's two hemispheres and their separate yet connected functions. They explain that if they are to improve their drawing skills they should get into their right mind.
Curated OER
Distance Formula
Learners create ways to find the number of square miles that lie in a triangle having vertices at A, B, and C. They compute the distance between two points and use Heron's formula to find the area of the triangle. Finally, students...
Curated OER
Where is it?
Students use a coordinate grid. They investigate and discuss what caused certain objects to be in specific places. They choose a room in their home to map and place objects in specific locations.
Curated OER
GPS Sports Field Activity
Students practice using GPS receivers and explore how knowing the coordinates of two locations allows them to determine the distance between those two points. They use the theory that they already had knowledge of and apply it to a...

Where in the World? The Basics of Latitude and Longitude
Students are introduced to the concepts of latitude and longitude. In groups, they identify the Earth's magnetic field and the disadvantages of using compasses for navigation. They identify the major lines of latitude and longitude on a...
Shakespeare in American Life
Tom Hanks and Caliban: Survivor Superstars
Here’s a clever way to combine language arts and social studies. Shakespeare’s The Tempest is believed to have been inspired by the wreck of the Sea Venture on Bermuda in 1609. The class views a brief scene from Castaway in which Tom...

Defining Regions Using Inequalities
Your young graphers will collaboratively play their way to a better understanding of the solution set produced by the combining of inequalities. Cooperation and communication are emphasized by the teacher asking questions to guide the...
Curated OER
The Next Dimension
Students explore the three dimensional Cartesian coordinate system and discuss how it is important for structural engineers in order to be able to describe locations in space to fellow engineers. They participate in a hands-on activity...
Curated OER
Finding the Way
High schoolers identify and research navigational tools used in deep sea explorations. They are introduced to a compass, the Global Positioning System and sonar technology and then describe their uses in underwater exploration.
Curated OER
Distance Formula
Students watch teacher demonstration of distance formula, view non-collinear cities on maps, plot points on coordinate plane, evaluate square roots, compute distance between two points, and use Heron's formula to find area of triangles.
Curated OER
Where Did It Come From?
Students research island formation, plot locations on a map and make an analysis of why some islands are formed where they are.

Why Does SSS Work?
While it may seem incredibly obvious to the geometry student that congruent sides make congruent triangles, the proving of this by definition actually takes a bit of work. This exercise steps the class through this kind of proof by...

Location, Location, Location: Using a Grid to Determine Context
Seventh graders are introduced to making inferences about artifacts. Using a grid system, they locate the artifacts and determine where they originated from. They use this information to make conclusions about the way people lived...

Gridding An Archaeological Site
Students investigate using some of the basic skills of an archaeologist while using a Cartesian coordinate system. They establish a grid system for a dig site and determine the locations for different artifacts. Students use the...
