Curated OER
Properties of Shapes
In this math worksheet, students look for the properties related to each shape and then fill in the graphic organizer with the categories needed.
Curated OER
Can You Build It?
Students investigate the concept of perimeter. They design there own figure and measure the perimeter of it. The lesson is given the context of the shape being a path that is traveled by a ladybug. This provides the shape of the plane...

A Geometric Scavenger Hunt
Fifth graders connect their knowledge of polygons and polyhedrons. In this geometric shapes lesson, 5th graders identify and classify two- and three-dimensional objects. Students construct a polyhedron out of polygons and describe their...
Curated OER
Octagon Lesson Plan
Students investigate octagons using words and shapes. In this geometry lesson, students discuss the shape of an octagon using physical and symbolic models. They make conjecture about the shape and relate it to the real world.
Curated OER
Geometry in the Real World
Eighth graders complete a unit of lessons on basic geometry concepts. They participate in a variety of activities, culminating in a project that involves publishing a booklet or a poster that presents the major geometry concepts from the...
Curated OER
Square Circles
Students find the perimeter and diameter of given shapes. In this square circles lesson, students measure circles and squares. They explore the relationship between the circumference of a circle and its diameter. Students examine the...

Geometry Review Quiz
Students conduct a review that is done right before having a geometry quiz. They cover major topics that are part of the assessment. They use review cards as notes to pass to one another to reinforce the concepts before putting them away...
Curated OER
Geometry Jeopardy
Students identify the pattern in a problem. In this geometry lesson, students make predictions, collect and analyze data. They apply the idea of scales and measurements to the real world.
Curated OER
Dream Bedroom Floor Plan
Students build and apply concepts of geometry. In this geometry lesson, students create a building using proportions and scale drawings. They use Cabri technology to create a virtual drawing first.
Curated OER
Dream Bedroom Floor Plan
Young scholars construct using Cabri software. In this geometry instructional activity, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the...
Curated OER
This Building is Tall
Learners calculate the perimeter of shapes. In this geometry lesson, students relate properties of polygons to the real world. They find length, midpoint and slope.
Curated OER
Sine and Cosine
Students solve problems using sine and cosine. In this precalculus lesson, students solve word problems using sine and cosine. They identify where it is appropriate to laws of sine and cosine and where to use the Pythagorean Theorem.
Curated OER
Calculating the Shortest Distance Between Two Points
Ninth graders calculate the distance between two points.
Curated OER
Peter's String
Students are introduced to the math problem and consider how they could approach it. In pairs, students investigate Peter's conjecture in any way they see fit. They then share their answers with the class.
Curated OER
Understanding Fractions
Students add and subtract fractions and multiply and divide fractions using pattern blocks.
