Graphing Linear Equations Using Data Tables
Learners review the Cartesian plane and the process of plotting points. In groups, students create tables, identify the slope and y-intercept, and graph the equation. Afterward, learners perform the same process, only, individually. As a...

Linear Equations Data Tables
Students graph linear equations on a Cartesian plane. After describing data tables and their use, students explore how the information from a table can be used to create a line graph. They discuss reasons for plotting a minimum of...

Graphing Coordinates
Sixth graders practice graphing coordinates. In this geometry activity, they use the x and y axis to locate points that must be connected in the right sequence to form a straight line.
Curated OER
X Marks the Spot
Fourth graders use games and puzzles to explore co-ordinate systems and their uses. Students are given the opportunity to invent their own systems by locating counters on a sheet of paper and by finding the dead center of a set of objects.
Curated OER
Transformations-Translations
Students perform transformations and translation on a coordinate plane. In this geometry lesson, students move shapes around on a graph identifying translation, image, and transformation. This lesson has an interactive part online that...
Curated OER
Chronic Conics
Fourth graders use two activities to draw four different conic sections. One activity is of a physical nature and one is traditional paper and pencil.
Curated OER
Slope and Parallel Lines
Students plot pairs of Cartesian coordinates on graph paper and connect points with straightedges. They examine the lines and determine if they are parallel or not by finding the equations of the lines and comparing the slopes. They...
Curated OER
Distance in Coordinate Geometry
Students analyze distance and graphing. In this geometry lesson, students work problems on a coordinate grid calculating the distance. They apply the Pythagorean Theorem to their data and answer.

Tessellation Sensation
Geometers investigate patterns and symmetry, and examine the artwork of M.C. Escher on the Internet. They compare his style to the floor and ceiling tiles in the classroom. If you have ImageBlender™ software, you could have your class...
Curated OER
Parallel and Perpendicular Lines
Fifth graders complete activities to investigate parallel and perpendicular lines. In this plane geometry lesson, 5th graders watch a movie about parallel and perpendicular lines. Students work in pairs to describe and draw the lines in...

Economics and emissions
Eighth graders produce a manufactured good and monitor energy consumption. In this Math lesson, 8th graders practice their basic math and accounting skills. Students participate in a business simulation.
Curated OER
Catch a Dream
Students apply the concepts of air pressure, the Bernoulli Effect, and angle of attack to build their own model planes out of paper, plastic, wooden rods, and drinking straws.
Curated OER
Triangles and Quadrilaterals
Second graders explore triangles and quadrilaterals. They rotate to various centers in the room to identify and examine triangles and quadrilaterals. After presenting a picture to the class, 2nd graders locate right angles, triangles...

Principles of Flight
Young scholars explore the principles of flight. For this flight lesson, students construct a model plane and investigate the forces acting on the flier. They will measure the thrust and calculate the stored energy.
Curated OER
The Flat Earth
Young scholars differentiate between different planes. In this geometry lesson, students differentiate between a plane and a sphere. They discuss the Great Circle, Geodesic and Lune as it relates to the earth.
Curated OER
Quilt Squares
Students research the history of the quilt in American History and view a PowerPoint Presentation. They create a quilt square with colored paper using polygons, transformations, rotations, and reflections on the computer and on a...
Curated OER
Graphing Functions With 2 Points and From a Graph
Students plot points on a coordinate plane. They describe, in words, methods for finding the slope of a line. After given a worksheet, students read instructions, draw a Cartesian plane, plot ordered pairs, and graph lines. Papers are...
Curated OER
10 by 10 Tessellations
Fifth graders, with a partner, create tessellation patterns by playing 10 by 10 Tessellations. They need to use critical thinking skills to decide if pattern block plane figures tessellate and how each block best fits into the pattern.
