Seven Circles II
Your learners find as many rigid motions of the plane as they can that are symmetries of the configuration of circles. Rigid transformations of the plane are explored and become more concrete to them as they visualize and execute these...
Leadership Challenge
Paper Airplanes
The first activity in this leadership forum asks pairs of participants to design and build a paper airplane and then fly this plane from one partner to the other. The debrief of the activity asks these future leaders to consider how they...

Reflection of Light
Students experiment with reflections of two plane mirrors placed at a 90 degree angle to see what will be reflected.
Alabama Learning Exchange
Human Slope
Middle and high schoolers explore the concept of slope. In this slope lesson, learners graph lines using a life-size graph. They use chalk on a blacktop to create a coordinate plane and use each other as the tick marks on the grid....

The Graph of a Linear Equation in Two Variables
Add more points on the graph ... and it still remains a line! The 13th installment in a series of 33 leads the class to the understanding that the graph of linear equation is a line. Pupils find several solutions to a two-variable linear...

Compound Inequalities and Graphing
Put geometry skills to the test! Learners solve compound inequalities and then graph the inequalities on a coordinate plane using their geometric skills. They identify the slope and y-intercept in order to graph correctly. I like this...

Investigating the Swissair Flight 111 Tragedy
Middle schoolers read two articles about the same event: "Plane from J.F.K Crashes off Canada" from the New York Times and "No Survivors from Crash of Swissair Jetliner Off Nova Scotia" from the Associated Press. They then compare the...

Geometry: Hide and Seek
A geometry game that resembles Battleship is the foundation for hide and seek where "hiders" draw shapes on coordinate planes and "seekers" must guess the shape and its location based on questions and clues. Reproducible, paper-sized...

Point Comparisons
Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

Solving Linear Inequalities in Two Variables
Although graphing a linear inequality on the plane is but a few steps added onto the graphing of a linear equation, for many learners the logical leap is quite intimidating. This approachable PowerPoint presentation breaks graphing...

Coordinates
What are your coordinates? After learning about coordinate systems in the real world, scholars see how a three-dimensional coordinate system works in Minecraft. They write a program to produce a compass rose and conduct an activity where...

Does Your Field Measure Up
Students measure angles using a plane table kit. In this geometry instructional activity, students use trigonometric identities to find the values of the length of a football field.

Investigation - Looking at Polygons
Middle schoolers construct polygons by plotting points on a coordinate plane. Pupils connect the points and identify which polygons they have drawn. They will need graph paper to carry out the assigned activities. A vocabulary list,...
Physics Classroom
All Work and No Play Lab
Don't let the term, "slotted wood board" detract you from the value of this experiment. Class members tie a string to a cart and, with even horizontal force, drag it up an inclined plane. The objective is to compare the work done with...

Graphics: Bits and Points
What can a mural teach pupils about computer science? The instructional activity has scholars create a mural on a wall to learn about bitmap and vector graphics. Along the way, they learn about the graphics coordinate system.

Linear Equations in Two Variables
Create tables of solutions of linear equations. A lesson has pupils determine solutions for two-variable equations using tables. The class members graph the points on a coordinate graph.
Virginia Department of Education
Inequalities
Compare graphing an inequality in one variable on a number line to graphing an inequality in two variables on a coordinate plane. Young mathematicians work on a puzzle matching inequalities and their solutions. They then complete a...

Stars and Slopes
More of a math lesson than physics or space science, high schoolers take a set of data and plot it on a log-log coordinate system. The write-up for day two was never completed, but day one, "Stars and Slopes," is complex and cohesive....

"A Slice of the Cone"
Here is a set of lessons that explore conics in a number of different ways. Starting with modeling how a conic is produced by the way a plane cuts the cone, to solving complex word problems, algebra learners progress through a series of...

Choose the Correct Homophone II
Homophones are tough! Identify different homophones and how they're different. Common ones like son and sun and plain and plane are included. Some uncommon ones are also included, like bridal and bridle.

Solution Sets
Here is a task that gives the graph of the solutions of a system of linear inequalities and asks learners to analyze and write the algebraic form of the systems. By turning the problem around, learners make the connections between...
