Curated OER
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 young scholars' skills when it comes to reflection on the coordinate plane.

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...

Points, Slopes, and Lines
Before graphing and finding distances, learners investigate the coordinate plane and look at patterns related to plotted points. Points are plotted and the goal is to look at the horizontal and vertical distances between coordinates and...
Curated OER
Polar and Cartesian Coordinates
Students review polar coordinates, as well as translations and rotations in Cartesian Coordinates. They also watch a video on conics and write a summary of the video for a quiz grade. Students then find an equation after a...
Curated OER
Geometry: Helix-a-Graph
Students use geometry to create art. In 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.
Curated OER
Graphing Candy-Coated Chocolates
Students place pieces of candy on their coordinate graphs as the teacher calls out the colors and coordinates embedded in the plan. The teacher circulates around the class to check each student's answers for accuracy.
Curated OER
The Trapping of Trapezoids
This is a nice hands-on activity where young geometers create trapezoids and calculate their area by looking at areas of quadrilaterals and triangles.
Curated OER
Collecting And Fitting Quadratic Data
Students investigate the concept of using quadratic data to plot coordinates on a plane. They also apply the quadratic formula for a variety of problems with the help of a graphing calculator to draw the parabola for given coordinates.
Curated OER
Comparing Data on Graph A and Graph B
Second graders gather and graph data. In this graphing lesson, 2nd graders collect data and graph this information using tally charts, bar graphs, pictographs, or tables. They make predictions about the outcomes.
Curated OER
The Trappings of Trapezoids
Students define trapezoids and their shapes. In this geometry lesson plan, students calculate the area of a trapezoid and a parallelogram. They use Cabri software to make investigations.
