Quilt Patch Proof
Students construct a convincing argument that the same amount of fabric is needed for each color of quilt being made in a specific design. They justify the relationship between vertical angles and the sum of the interior angles. Students

Exploring and Creating Tessellations
Young scholars use translations, rotations, and reflections to create tessellations. They explore and construct several different types of tessellations including pure/semi-pure and non-regular polygon and "Escher-like" tessellations .
Curated OER
Don't Box Me In
Pupils explore the relationship between flat and three-dimensional shapes. They identify the names of 3-D shapes and construct cubes from squares.
Curated OER
Tangrams
Young scholars construct the tangram pieces from a square paper by following directions to fold and cut. They make observations on the pieces formed and compare how they are related to each other. They explore patterns and shapes with...

Polygon Perimeters
Fourth graders practice finding the perimeter of shapes. In this measurement lesson, 4th graders review the meaning of perimeter and work in groups to draw polygons with differing perimeters. Students share their polygons with the class.

Straw Bridges
Pairs work as engineering teams to design and build model bridges from drinking straws and tape. In this third segment in a series of 10, teams compete in an attempt to build the strongest bridge. To help with the design, the groups...
Curated OER
Geometry Practice: Loci and Transformations
This resource guides young geometers to create new polygons from others of equal area, compare an image to its reflection and find errors, conduct repeated reflections, map translations, and determine center of rotation. No solutions are...
Curated OER
Exploring Pythagorean Theorem
Eighth graders explore the Pythagorean Theorem. They use Geometer's Sketchpad and explore features of various figures. Students use the software to build a figure using the given measurements.
Curated OER
A Honey of a Hexagon
Students explore how bees make honey and why the hexagon is the best basic pattern for the honeycomb through the use of a video and hands-on activities with honeycombs and geometric shapes.
Curated OER
Transformational Geometry Using the Geometer's Sketchpad
Students complete a webquest on the various types of symmetry. Using a computer, they explore the concepts of transformational geometry and identify points, segments, lines and planes. They experiment with the rotation of a quadrilateral...

ExplorA-Pond:3rd Grade Shapes & Fractions
Learners, using a map, drawing or aerial view of a pond, represent the shape of the pond using simple geometric shapes or fractions of those shapes. They identify the numerator and denominator in each fraction created.
Curated OER
Geometric Pictures of One Half
A learning task that involves creative ways of thinking permits children to use paper models as a way to visualize the fraction one-half. Learners can fold or cut their models in such a way that the unshaded regions, and shaded regions...

Egyptian Numeration Pyramid
Fourth graders, using paper, construct a 3-D pyramid, decorating it with Egyptian numbers.
Curated OER
ndirect Measurement Technique: Using Trigonometric Ratios
Ninth graders find the height of an object that would be difficult or impossible to measure directly. They construct and use a Clinometer to measure the angle of elevation (or depression). Students create a sketch of the measurement...
Curated OER
Listen to a Shape
First graders identify basic shapes (circle, square, rectangle, triangle) and describes the attributes of each. They use magazines to find examples of each shape, and then make a collage.
Curated OER
Geometric Figures
Students compare, classify and calculate the area of geometric figures such as rectangles, squares, circles and triangles.
Curated OER
Angles, Parallel Lines, and Polygons
Learners examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...
Curated OER
Shape It
Fourth graders use math software and geoboard paper to design basic shapes. They write individual definitions for the geometric shapes based on what they see in the shapes. They apply their background knowledge of the shape as they write...

Bill's Badge
Students explore the making of circles and concepts related to them in geometry. The project is inquiry based will focus upon students making their own nametags. The construction is ideal for hands on students.
Curated OER
Pyramid Play
Students investigate the concept of the Food Pyramid. They use a game as a tool of discovery in order to classify different types of food in the pyramid. Upon completion of the game the students construct their own models of it.
