Dimensional Flower Garden
Students relate the colors in a garden to those in a rainbow by creating a multicolored three-dimensional garden portrait. They read, "Planting a Rainbow" by Lois Ehlert, then construct their garden with colored paper on white cardstock.
Curated OER
Watching Wheatstacks
Students explore basic shapes in Monet's paintings Wheatstacks, Snow Effect and Morning. They study about light and shadows through reading and experimenting with three-dimensional models and flashlights.
Curated OER
Scaling Down the Pyramids
Learners construct three-dimensional models of the three pyramids at Giza. They research the building of the pyramids and record the height, base and angle measurements of each pyramid. They create a file of facts regarding the pyramids.
Curated OER
Length, Perimeter and Area
Learners analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationship
Curated OER
If I Had a Robot
Students study writing. In this creative writing lesson, students write a story about having a robot and make a three-dimensional robot to accompany their writing.
Curated OER
Fantasy Creature
Students, in groups, create three-dimensional sculptures from found objects. They paint their sculptures and write essays that reflect on the collaborative creative project.
Curated OER
Investigating Lengths of Segments in a Triangle
Pupils explore the midsegment of a triangle in the geometry lesson plan. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the triangle. The...

Vasarely Was A Colorful Fellow
Eighth graders create artwork inspired by the work of Victor Vasarely. In this op art lesson, 8th graders explore color theory and color mixing. Students create ten shapes to use in their artwork and over the course of two weeks,...
Curated OER
Polygon Perimeters
Students complete worksheets where they calculate the perimeter of polygons. In this perimeter of polygons lesson plan, students divide complex shapes into simple shapes to find the perimeter.
Curated OER
Polygon Perimeters
Students define the terms polygon and perimeter to begin the lesson. Using a calculator, they practice determining the perimeter of various symbols in a painting. They discuss how geometry and art are related to one another.
Curated OER
A Holocaust Monument
Pupils examine Holocaust memorials to discover expressive power of shapes, practice creating simple geometric shapes or forms, and practice calculating ratios, area, and/or volume.
Curated OER
A Holocaust Monument
Students create a Holocaust memorial. For this interdisciplinary lesson, students use geometric shapes or forms to create a Holocaust monument.
Curated OER
Isosceles Triangles
Students investigate triangles. In this shapes geometry lesson, students define and state the attributes for equilateral, scalene, and isosceles triangles. Students locate the prefix "tri" in a variety of words and make connections with...
Curated OER
Salad Tray 3D Topographic Model
High schoolers explore the characteristics of topographical maps. They examine the relationship of contour lines and vertical elevation. Students create a three-dimensional model of a landscape represented by a topographic contour map.
Curated OER
Angles ~ Right Angles
Have your class review how to identify right angles. Learners identify right angles, and then write the number of angles found in each shape.
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...
K12 Reader
Basic Geometry Terms
Set your pupils up to start on geometry by teaching them some introductory terminology. Pupils learn the terms by reading a short passage and looking at examples. They then respond to five questions related to the text.
Curated OER
Area of Tangram Pieces
Mathematicians calculate the area of a tangram piece without using formulas. They use a geometry journal to record activities during this lesson. They make a set of tangrams and use them to compute area. They use...
Curated OER
Teaching About Plate Tectonics and Faulting Using Foam Models
Young scientists learn about plate tectonics and the three different types of faults (normal, reverse, and strike-slip) using foam models. The activity also covers common types of locations where these faults are found.
Curated OER
Introduction to Minerals
Students discover how crystal structures go together to create minerals. In this earth science lesson, students work in groups to create 3-dimensional shapes of crystals that they then put together in a compact structure.
Curated OER
Shapetown
Students identify basic geometric shapes. In this geometry lesson, students read the book Shapetown and identify the various shapes from the story. Students are given a sheet and draw part of a town using only shapes.
Curated OER
Protein Puzzles
Students examine the concept of protein structure. They read an article, construct a three-dimensional model of an insulin protein, take a quiz, conduct Internet research, and answer discussion questions.
