A comprehensive list of 2D shapes and 3D solids with everything from a triangle to a dodecahedron. Includes illustrations and short descriptions of attributes for each.

In this lesson, students will create a shape mobile of 2-dimensional and 3-dimensional shapes made from geometric shapes.

Identify and compare shapes based on their attributes. Shapes include triangle types, quadrilateral types, pentagons, and hexagons. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video...

My first graders have been studying the defining attributes of 2D shapes. They are going to love using toothpicks and marshmallows to present their knowledge of 2D and create 3D shapes.

In this lesson on plane shapes, students will learn to identify 2D shapes by their attributes, and will apply these shapes to those in the world around them.

Classify shapes based on pictures or attributes, such as angle types and side-lengths. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

In this lesson plan on solid shapes, students will learn to identify three-dimensional shapes by their attributes and learn to recognize them in the real world.

First graders begin to learn about plane shapes in Kindergarten. This lesson will serve as review of plane shapes' characteristics and extend into practice in categorizing shapes by defining attributes.

Clean Up this Mess! The classroom shapes are in one big heap. Students will work in teams to come up with a way to sort the shapes by attributes and create a visual representation to model their thinking

In this lesson on 2D shapes, 3rd graders will learn to discriminate quadrilaterals from other polygons. Additionally, they will be able to identify attributes of a square, rectangle, and rhombus.

Practice identifying circles, triangles, squares, rectangles, rhombuses, trapezoids, and hexagons. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Students work in pairs and take turns drawing two cards. These cards have pictures of different shapes. The students are asked to describe what is similar or different between the two shapes. This type of task lays the foundation for the...

Students will explore shapes and their attributes through a variety of resources including web sites, story books and manipulatives. Students will create a presentation of a shape adventure.

The Chinese character mark formerly known as "Tan" is the first of two lessons to introduce first grade students to geometry using tangrams. This lesson plan incorporates history, math, and language arts. In this lesson plan students...

Origami (ori-folding, kami-paper) is the traditional Japanese art of folding paper. Learners will discover relationships between shapes as they are actively engaged in this hands on geometry activity to learn basic geometric shapes,...

Can you judge an object by its shadow? Use your mental rotation skills to determine if a shadow can be produced by a particular shape.

The Chinese character mark for Tan II (pronounced she-tow-bah) is the second of two lessons to introduce first grade students to geometry using tangrams. This instructional activity incorporates history, math, and language arts. In this...

As a whole group, students will sort a collection of three-dimensional objects into categories by shape. There should be several that fall into each of the categories below: Aligns with 1.G.A.1.

At early stages of understanding of geometric shapes, 4th graders describe shapes, but do not yet characterize shapes by their properties. One example of a misconception students have at this stage is that a rectangle has two short sides...

A guide to support parents as they work with their students in identifying, composing, and partitioning shapes.

Students will use their knowledge of plane figure attributes to create and view shapes by cutting and rotating shapes to stimulate discussions on names and attributes of various shapes they do not regularly encounter.

This activity tests the student's understanding of patterns. The teacher will read a pattern and the student will find the row or column that contains each sequence. Example included.

Investigate the relationship between shapes and identifying traits or characteristics. A concise lesson that explores physical, chemical, and observable traits in the shapes around us. Build on this knowledge by playing the Web Colors...

[Free Registration/Login Required] In this flipchart, students use the drawing and interactive tools in Activstudio to apply geometric properties and relationships to describe, compare, and draw two-dimensional shapes and figures.
