Standard Treehouse Lesson Plan
Seventh graders investigate the concepts related to the geometry of treehouses that focuses on angles that are similar and congruent. They conduct class discussion in terms of looking at three dimensional shapes that are represented in...
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 identify two and three dimensional shapes and use appropriate geometric vocabulary to write a description of the figure by taking pictures of geometric figures in their own environment.

Nets of 3-Dimensional Figures #2
In this nets of figures worksheet, learners determine which given shapes will make a shown net, then name the shapes uses. A reference web site is given for additional activities.
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...
Curated OER
Net C
In this learning tool worksheet, 3rd graders cut and paste a template to create a cylinder. Students could color or decorate the cylinder.
Curated OER
Surface Area
Sixth graders compute the surface area. In this surface area instructional activity students are given a set of problems to calculate. They compute the surface area of cubes and rectangular boxes.

An Introduction to Measuring Theory
Students investigate one, two and three dimensional objects. In this algebra lesson, students differentiate between different shapes of objects and write equations to represent each. They start with what they already know and prove...
Curated OER
Sketch Up
Students estimate and measure exact. In this geometry instructional activity, students create different object in three-dimensional pattern. They use SketchUp to create their shape and perform measurements on their shapes.
Curated OER
Leather Mardi Gras Mask
Students examine different masks from Mardi Gras. They discover the culture of the area and create their own mask. They use leather to make the mask three-dimensional.

A Classroom Demonstration of Protein Folding
Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank stares?...
Curated OER
A Rectangular Prism and Its Net
Identify the nets for prisms and other geometric shapes. Learners calculate the surface area of the rectangular prism then sketch the shapes of prisms and other polygons. Unfolded cereal boxes are used as a visual aid, great idea!
Curated OER
Ruler and Compass Constructions
Fourth and fifth graders examine how to construct perpendicular lines and to bisect angles using rulers and compasses in this unit of lessons. They design a number of polygons using these methods.
