3rd Grade Math - Geometry & Spatial Sense

Visit Internet 4 Classrooms for other great 3rd grade links!

Three-Dimensional Shapes (lesson plan) - In this activity, students will identify shapes that architects use to build houses. Students will then explore these shapes by building a model of their "dream" home.

Geometry & Measurement (lesson plan) - After reading the book Flat Stanley the students will be able to determine the difference between two dimensional and three dimensional shapes.
 

Plane Figure

Review Solid Figures - from Georgia Learning Connections; teaches students to understand the concept of plane figures and shapes and their traits.
3D, Dude! - uses real-life objects to teach shapes.  Shape flash cards are made that can be used for reinforcement; from Georgia Learning Connections.
Shape Riddle Book - from Georgia Learning Connections; students create a riddle book to share with other students.
Geometric Houses - identify the parts and functions of a house by creating a house made of geometric shapes.
Shape Up! - Jump ropes are used to review the shapes of triangle, rectangle, square, and circle; from Georgia Learning Connections.

Congruence, Similarity

Chip Off the Old Block - from Georgia Learning Connections; identify and group figures according to characteristics using Venn diagrams.
Congruent Companions - from Georgia Learning Connections; work with peers to discover congruent shapes.
Relationship Review - students go on an expedition to find similar figures and congruent figures; from Georgia Learning Connections.
Sorting Shapes - use congruency to sort and categorize shapes; from Georgia Learning Connections.

Symmetry

Symmetry Quilt - from Georgia Learning Connections; learn about symmetry by creating a pattern for a quilt block.
Geometry Activities - construct 2-D and 3-D shapes which we hang on an evergreen tree appropriately labeled our "geometree".

Visualization

Surrounding Shapes - develop spatial reasoning by using clip art from the Internet.

Combine/Subdivide Shapes

Totem Poles on the Rise - students use different shapes to create their own totem pole.
