Coordinate Geometry
Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...

Reflecting Reflections
A triangle rests in quadrant two, from which your class members must draw reflections, both over x=2 and x=-2. This focused exercise strengthens students' skills when it comes to reflection on the coordinate plane.

Geometry- Coordinate Plane
Students plot points on a coordinate grid. In this coordinate plane lesson, students use a coordinate grid to locate the perimeter points of pictures, identify quadrants and use the coordinate points to draw the picture on a blank...

1st Geometry
In this geometry worksheet, learners choose the multiple choice answer to 15 questions involving several different elements of geometry.

Unit Squares and Triangles
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 and angle...

Geometry: Helix-a-Graph
High schoolers use geometry to create art. For this geometric graphing and patterns lesson, students create a helix-a-graph by plotting points on a grid that follow a certain pattern and analyze the drawing they created.

Let's Plot Points
Use coordinate grid paper to plot points and identify shapes that are already plotted on the paper by saying their coordinates. Pupils also measure the distance between points and play the game Battleship. There are several web links and...

Segments That Meet at Right Angles
Can segments be considered perpendicular if they don't intersect? Learners look at nonintersecting segments on the coordinate plane and make conclusions about the lines that contain those segments. They determine if they are...

Point Reflection
Use this task as an exit ticket for your eight graders during the geometry unit. All they need to do is identify the coordinates of a point reflected over y=2000.Â
Balanced Assessment
Square in Square
Challenge the class to devise a method to determine the dimensions of a rectangle inscribed in another rectangle. Pupils make connections between functions and geometry as they examine the area and perimeter of a square or rectangle...

Pixar: The Math Behind the Movies
When will we ever use this? A Pixar movie maker explains to students how math is used in the creation of animated films. The movie maker discusses the importance of coordinate planes, transformations and translations, and trigonometry.

Lines in the Coordinate Plane
Students graph lines in a coordinate plane. In this geometry lesson, students graph lines on a coordinate plane, and identify the slope. They classify the lines as parallel or perpendicular and write an equation of a given line.

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...

Dilation
Open up your pupils' eyes and minds on dilations. Scholars perform dilations on a trapezoid on the coordinate plane. They compare the image to the preimage and develop generalizations about dilations.
