Basic Right Triangles
Elementary schoolers examine the attributes of triangles. In this triangle lesson, learners compare regular triangles and right triangles. They explore vertices and angles and investigate obtuse and acute angles. Pupils draw multiple...
Curated OER
Dimension in Art
Third graders consider space and the techniques artists use to create three-dimensionality within a painting or drawing. They examine works by Millet, Bruegel and Demuth and then create original drawings that explore the effects of...
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.

Nets of 3-Dimensional Figures #2
In this nets of figures worksheet, students 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
A Cylinder and Its Net
Students sketch the nets for given polygons and cylinders. In this geometry lesson, students find the measurements that correspond with prisms, cones and cylinders. they identify parts of three-dimensional shapes.
Curated OER
Pyramids on Parade/Nets
Students sketch the shape of three dimensional pyramids using nets. In this geometry lesson, students differentiate a pyramid from other three dimensional shape. They define the attributes of pyramids.
Curated OER
Exploring Secants: Products of Segments
Students explore secants and circles. In this geometry lesson, students identify the properties of two and three dimensional shapes. They create arguments to prove the theorems are true.
Curated OER
Surface Area of Cones
Students find the surface area of cones. For this geometry lesson, students calculate the dimensions of each three-dimensional shape and use the correct formula to solve the problem. They relate concepts of cones to the real world.

Patterns and Fingerprints
Human fingerprint patterns are the result of layers of skin growing at different paces, thus causing the layers to pull on each other forming ridges. Here, groups of learners see how patterns and fingerprints assist scientists in a...
Curated OER
If I Had a Robot
Learners 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
Perimeter and Area of 2D Shapes
Students find the perimeter and area of circles, triangles, and rectangles. In this perimeter and area lesson, the teacher gives students formulas for each shape and measurement and works through examples on the board. While no creative...
Curated OER
Investigating Nets and Polyhedra
Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...
Curated OER
Faces, Vertices, Edges
Learners identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

Making a Paper Cube Using a One Dimensional Net
In this geometry worksheet, students make a paper cube by following the directions given on the paper, They cut along the outside edge of the net, fold inward along the inside lines, and glue the flaps to hold the shape of the cube.
Curated OER
Slimy Cells
Students create three-dimensional cell models. They may choose to make either a plant or animal cell but must use a Ziploc bag as the cell membrane, slime for the cytoplasm, and strawberry baskets for the cell wall if making a plant...

3-D Texture Painting (Impasto)
A neat art project is on the horizon. Your class can experience impasto, or textured painting with this expressive art lesson. They design and then paint using the impasto technique. This is done by mixing toilet paper into the paint....
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
Perimeter All Around
Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.
