Third graders explore the attributes of polygons. In this geometric shapes instructional activity, 3rd graders review quadrilaterals, squares, rectangles, triangles, pentagons, hexagons, and octagons in order to create hanging polygons....

Students investigate measurement through the use of literature through this series of lessons.

Third graders identify two and three dimensional shapes used in architectural designs by viewing images on the Internet.  In this geometry lesson, 3rd graders create their own building designs and identify the geometric shapes that...

Students discover math measurements by creating a skit with classmates.  In this geometry lesson, students utilize objects in a paper bag and index cards to create a short skit focusing on debate over the size of the objects....

Students explore measurements by analyzing geometric shapes. In this surface area lesson plan, students identify the terms volume, weight, perimeter and area in order to find the requested measurements of specific polygons. Students...

Students investigate architecture and construction by building a home from cardboard tubes.  In this housing lesson, students collaborate in groups to plan and create buildings they can fit in made from cardboard tubes, newspaper...

Students build towers from recycled materials. in this building lesson, students build the highest tower they can from varied materials. They focus on shapes and which items should go on the bottom to make a strong base. 

Students investigate geometric shapes by creating figures on a plane. For this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

Students construct a set of tangrams. In this geometry lesson, students read the book, Grandfather Tang's Story and retell the story using tangrams. Students construct their own set of tangrams using the included worksheets.

Students use pattern blocks to create a figure that is described to them and establish a pattern based on the description of the geometric figure. For this pattern blocks lesson plan, students fill out shape and fraction worksheets.

Third graders draw shapes that are congruent with each other and identify other congruent shapes. In this congruency lesson plan, 3rd graders also apply specific colors from the color wheel in their shapes.

Practice factoring numbers by using graph paper, manipulatives and computer applets.

Students generate a list of numbers then classify them into groups of single digit and double-digit numbers. After listening to a children's book about double-digit addition, they work with tens and ones blocks to solve double-digit...

Help your students explore shapes. They classify shapes and identify them in their everyday world. Plane shapes are explored, and they classify and identify the plane shapes.

Students create various geometric shapes with their younger grade "buddy partners." They identify and discuss various geometric shapes, and using gumdrops or marshmallows and toothpicks, construct different flat and three-dimensional...

Students investigate solid shapes. In this geometry activity, students take pictures of solid shapes and classify their pictures according to the vocabulary terms: edge, face and vertex. Students present their findings to the class.

Students construct tangram patters. In this geometry lesson, students read the book Grandfather Tang's Story and visit various websites to practice covering figures with tangrams. Students attempt to construct animal shapes using puzzles.

Students investigate geometric shapes in their environment, make a geometric design, and write paragraphs describing the design.

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Students examine the process of drawing a picture to scale. They analyze and discuss real-life blueprints for a house, and create a scale drawing of an original invention using calculators and rulers.
