Sample Lesson Plan on Lines and Angles
Student complete worksheet using the definitions of lines and angle vocabulary. They define the word and follow a direction given on the worksheet such "construct a line." They complete an online tutorial on how to measure angles using a...
Illustrative Mathematics
Reflections and Isosceles Triangles
Geometers explore symmetries of isosceles triangles by using rigid transformations of the plane. They complete four tasks, including congruence proofs, which illustrate the relationship between congruence and rigid transformations. The...

Who Am I? (Middle School)
Third graders complete a classroom game used to build understanding of two and three-dimensional shapes. Diagonals, sides, regularity, congruency, angle measurements, parallels, perpendicular, faces, and edges are a few of the vocabulary...
Curated OER
Don't Box Me In
Students explore the relationship between flat and three-dimensional shapes. They identify the names of 3-D shapes and construct cubes from squares.
Exploratorium
Exploring a Complex Space-Filling Shape
Middle schoolers build a three-dimensional 12-pointed star as a geometric exercise. The shape is quite-difficult to construct. Luckily there is an excellent template that learners cut out, then use to make their pyramid. The second part...
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...

Spatial Relations - Week 9
In this spatial relations worksheet, learners solve three-dimensional problems. They find the total number of triangles in a given figure, the number of line segments that endpoints and use integer points to solve two problems. This...
Curated OER
Make a Box
Students use specific dimensions to create a box. In this geometry lesson, students analyze the different properties of two and three dimensional shapes. They make conjectures and use it to solve problems.
Curated OER
Artistic Angles
Fifth graders explore angles by using protractors. They recognize, describe and determine the surface area and volume of three-dimensional shapes. Students recognize the right angle, acute angle, obtuse angle and vertex. They identify...

Making Cubes
Third graders explore vocabulary associated with three dimensional figures. In this transformations lesson, 3rd graders create two dimensional nets for three dimensional figures. Students become familiar with describing two...
Curated OER
Sculptural Heads
Students create sculptures of a human head with Sculptamold. They discover the differences between two and three dimensional art. They combine art history, aestetics and personal expression to create a sculpture.
Curated OER
Polyhedra Book
In this math worksheet, students are asked to read the book that focuses upon the creation and explanation of three dimensional shapes.
Curated OER
2D Polygons and 3D Nets
Students compare and contrast two dimensional polygons and three dimentional nets by examining the differences in drawings. They create three dimensional shapes and label the faces, edges, and vertices. After creating the shapes, they...
Curated OER
Measuring Body Angles
Students use technology to graph and compare angles. For this geometry lesson, students range of motion in the environment. They identify the missing parts of polygons using similarity and congruence.
Curated OER
Keith Haring and Graffiti
Young scholars appreciate the art of the artist Keith Haring. They design and implement Keith Haring-like images for a wall mural and explain and experience a project containing many different compenents and processes from beginning to end.
Curated OER
Interactivate - Lines, Rays, Line Segments, and Planes
Middle schoolers explore lines, rays, line segments, and planes. For this math lesson, students discuss the math concepts and direct their instructor in graphing functions. Middle schoolers collaborate in graphing additional functions.
Curated OER
Cubes Everywhere
Students use cubes to construct and visualize two-and three-dimensional shapes to develop spatial thinking and review basic geometric principles through real-life applications. They are given the opportunity to build and build and take...
Curated OER
Identify Solid Shapes
In this solid shapes worksheet, students name and describe the solid shapes on the left. Students color the objects that are like the solid shape.

How Do 3D Printers Work?
If we stack up all the cross sections of a figure, does it create the figure? Pupils make the connection between the complete set of cross sections and the solid. They then view videos in order to see how 3D printers use Cavalerie's...
Mathematics Vision Project
Module 7: Modeling with Geometry
Model good modeling practices. Young mathematicians first learn about cross sections and solids of revolution. They then turn their attention to special right triangles and to the Laws of Sine and Cosine.
Curated OER
Attributes & Nets of a Cube
Third graders engage in a lesson that focuses on the attributes and forming of a cube. They construct a cube using different combinations while comparing a square with only two-dimensions. Students fold paper while following the...

Creating Relief Sculpture
Students design and create a sculptural relief using modeling clay.They create latex rubber molds and then produce relief sculptures using Sculptamold.
Curated OER
Analyzing 3-D Shapes and 2-D Representations
Students can analyze 3-D objects better with actual physical models and by also drawing 2-D representations of them.
