Young scholars learn five songs to define and develop understanding of the attributes of two- and three-dimensional figures and the meaning of mathematical terms. They classify objects as either two- or three-dimensional, through the use...

Learners are asked to visualize three-dimensional figures and apply this visualization to problem solving.

Each of these 10 shapes comes with a question for learners to answer as they analyze its attributes. They examine the following shapes: hexagon, trapezoid, pentagon, circle, diamond, parallelogram, rectangle, triangle,...

Students investigate the volume of cones. In this geometry lesson plan, students define the formula to find the volume of cones. They define the concept of having to dissect a three dimensional figure and find the volume.

It's the parts that make the whole. Learners apply volume formulas to composite figures to find the total volume of the figure. Previous lessons in this series taught the methods for finding the volume and/or dimensions of...

How much can different shapes hold? The answer varies depending on the shape and dimensions. Individuals learn the formulas for the volume of a sphere, cone, and cylinder. They apply the formulas to find the volume of these...

In this geometry activity, 6th graders study comprehensive facts pertaining to volume and measurement of geometric, three-dimensional figures. Students solve for 59 problems showing their work.

Explore two and three-dimensional shapes. Learners first examine three 2-D shapes and determine which of three 3-D figures could have made that shape. The wording here is a bit confusing; make sure your kids understand what it is...

Students judge, compare and construct two-dimensional figures using a variety of materials.

Pupils find two dimensional shapes in three dimensional figures. They determine the shapes that make up the faces of three dimensional figures of common classroom objects such as crayon boxes.

Students compare and discuss characteristics and properties of 2- and 3-dimensional shapes. They construct 3-dimensional paper star figures, imaginatively customizing them with art tools and craft materials. Students analyze their...

Explore the relationship between 2D and 3D shapes by having your class view representation of shapes and investigate their symmetry. They will create a solid object from diagrams and describe the reflection or rotational symmetry. In the...

Aspiring astronauts construct a space vehicle using cylinders, cones, spheres, and rectangular prisms. This is an engaging method of learning about three-dimensional shapes. Note that the word cylinder is constantly misspelled in the...

Discover the connection between vectors and translations. Through the lesson plan, learners see the strong relationship between vectors, matrices, and translations. Their inquiries begin in the two-dimensional plane and then progress to...

What do you get when you slice a prism? Pupils discover that the answer depends on how the prism is sliced. The second half of the 29-part module focuses on three-dimensional objects. Learners use their two-dimensional vocabulary and...

Geometry can be fun when you know the shapes! Twelve pictures of geometric shapes, including cones, pyramids, and spheres, prompt first graders to write the name of each shape in the space provided. Use the activity as a quiz or homework...

It's time to discover what your classes have learned! The final lesson in the 25-part module is an assessment that covers the Pythagorean Theorem. Application of the theorem includes distance between points, the volume of...

Pupils complete a review activity that highlights the key problems from the first eight lessons in the series. Topics include the Pythagorean Theorem and its converse, as well as finding volume of three-dimensional figures.

Whether you're using it to tell stories, explore the letter b, or during a life science lesson, these butterfly puppets will be a hit. Youngsters use crayons, tissue paper, and paper bags to create butterfly puppets.

Fifth graders draw 2-D and 3-D shapes. They sketch and label geometric figures with correct terminology, then explore parallel and perpendicular lines. Pupils sort and classify shapes drawn.

The task at hand is to partition a hexagon into two, four, and eight congruent figures. Make sure to give your wizards a sheet of triangle grid paper on which to decompose the hexagons. Have them explain which rotations, reflections, or...

Writing can become one-dimensional if authors don't involve all their senses. First, scholars observe a strange object which, ideally, they can touch and even smell. Without using certain words (you can create a list or have the class...

The Olmec were an ancient people native to Mexico who lived from 1000-500 BC. Young artists examine the Olmec piece Seated Figure to analyze the use of body language to communicate a tone or feeling. They then use clay or play-dough...

Seventh graders measure surface area. In this geometry lesson, 7th graders find the surface area of various geometrical shapes. Using a computer program, students compute the area of 2-D and 3-D shapes.  Students use...
