Learners honor mathematicians who have contributed important discoveries throughout history by researching and creating a report about a famous mathematician and their contributions to the history of mathematics. Pairs of learners...

Learners play a "Battleship" type of game to practice graphing on a coordinate plane. In this coordinate graphing instructional activity, students select a point on their grid to place their "battleship." It the opposing team misses the...

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.

Middle and high schoolers participate in a seven-part lesson plan creating Escher-Esque tessellations. They demonstrate their knowledge of geometric transformations after viewing a PowerPoint presentation, conducting Internet research,...

Create the ultimate miniature golf course. The 93-page model curriculum unit from the Massachusetts Department of Elementary and Secondary Education contains nine lessons on understanding similarity in terms of both Euclidean geometry...

Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...

Study geometry through the concept of quilt design. High schoolers examine the geometric shapes in various quilts and then create their own quilts using geometric shapes that fit together. In the end, they write a paragraph to...

Students read The Greedy Triangle and discuss geometric solids. In this geometry lesson plan, students list the geo-solids in the world and create a graphic organizer to show where geo-solids exist.

Primary geometers create a picture using tangrams. In this geometry lesson, students read Grandfather Tang: A Tale Told with Tangrams, cut out their own tangrams, and choose a character from the story to make using their tangram pieces.

Students identify symmetrical and congruent elements in folk art. In this art and geometry lesson, students examine pictures of Masonic Plaque in the Form of a Royal Arch Tracing Board for evidence of congruent and symmetrical elements....

Students measure prisms and determine their volume. In this measurement and reasoning lesson, students estimate the volume and area of prisms. They measure given boxes. Students use paper to create prisms and cylinders. They determine...

Students build replicas about nature and sports. In this geometry lesson plan, students build 3D replicas of nature and sports objects in teams.

Students study the architectural designs of different popular sites. In this math lesson, students draw a grid diagram. They explain what geodesic algorithms are used for.

Learners explore the different methods used in celestial Navigation and astronavigation. In this math lesson, students construct a sextant and demonstrate how it works.

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...

Students identify and name different geometrical shapes. In this math lesson, students distinguish odd from even numbers. They describe the properties of 2 and 3 dimensional objects.

Learners examine the concepts of geometry used by Paul Goble in his book Adopted By The Eagles. After analyzing Mr. Goble's work they create an original piece featuring symmetry, pattern, repetition, and other principles of geometry....

Students learn how to identify cell addresses, format cell contents, add pop-up comments to a cell, and also apply conditional formatting. They use clues and words to make a geometry crossword puzzle pertaining to geometrical shapes.

New-to-school learners create a fall quilt consisting of three different paper geometric quilt squares. They use various geometric shapes that when assembled will form a scarecrow, pumpkin, and a crow. Assembly will require sorting...

Students use the inequality theorem to solve triangles and their properties. In this geometry lesson, students are given spaghetti of different lengths and asked to create triangles. They conclude the necessary length needed to make a...

Students explore simple patterns.  In this mathematical thinking geometry lesson, students repeat clapping and snapping patterns, and determine what comes next in sound and movement patterns.  Students recite "Hey, Diddle,...

Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade...

Learners investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects and...

Learners analyze the amount of space required to pack round objects. In this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...
