Module 5: Modeling with Geometry
Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Polygons and Plane Figures
Students choose a polygon to define and describe, and use Power Point and the Internet to present their polygon.
Curated OER
Simple Machines
Students explore the concepts of force and effort by observing simple machines. In this physics lesson, students attempt to sharpen a pencil without any help, bite into an orange with their lips curled over their teeth, and other...
Curated OER
Rotational Symmetry
In this rotational symmetry learning exercise, 10th graders identify and compare 10 different figures illustrated on the sheet. They write the order of rotational symmetry seen in each figure as compared to the others. They also define...

Battleship Wisconsin
Students predict what geometric shapes they think would be on the battleship; then view a picture and identify the various shapes they see. They take a tour of the battleship Wisconsin they identify various geometric shapes represented...
Curated OER
And The Twelfth One Is
Ninth graders play guess my shape (either describe or use a feely bag to introduce the 3 shapes in the problem.) As they are identified put them in an order as shown in the problem. As the students work on the problem in pairs teacher...
Curated OER
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...
Improving Measurement and Geometry in Elementary Schools
Rep Tiles
In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Circles: A Geometric Perspective
Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

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,...

Dog Gone Again!
Here is a real-life lesson! Learners must plan the dimensions of a rectangular fence to reign in a runaway dog. They survey what shape and size fence is needed and use formulas to find perimeter and area of the fence. They explore what...

Lesson 2-5: Absolute Value Functions and Graphs
What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign. They graph each function on a coordinate plane and identify the maximum and...

Hexagonal Pattern of Beehives
Young geometers and biologists investigate the math of nature in an activity that is just the bee's knees. Participants will study the tessellations of hexagons in a beehive, along with the natural rationale behind the specific shape....
Curated OER
Geo Jammin By Design: Coordinated
Learners watch the teacher draw on the chalkboard and try to determine the form being drawn. They use questions to determine Quadrant #1 of a coordinate plane.
Curated OER
Geometry House!
Fourth graders use computer drawing tools to create a house of geometric shapes.

Meet the Polygon Family
Fourth graders investigate regular polygons. In this regular polygon lesson, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.
Curated OER
Rap-Tap-Tap
Fifth graders investigate incline planes and wedges. They identify a variety of incline planes and wedges that are found all around them. Students record their findings using a worksheet.
Curated OER
Geometry in Tessellations
Students examine tessellations and their geometric properties. Students also develop a better understanding of lines, planes, angles, and polygons.
Curated OER
Self Check Practice
In this planes worksheet, students solve 5 multiple choice problems. Students determine which planes intersecting create a given line. Students determine which point is coplanar with three other ones.
Curated OER
Impossible Graphs
Middle schoolers distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane
