How  does the shape of the surface of water in a container change as water leaks out? After tackling this question, learners take part in a similar activity with more complex figures.

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Young mathematicians look at five 3-D shapes and name them based on the accompanying image. For each shape, learners state the number of faces, vertices, and edges.

Engage youngsters in exploring the wonderful world of shapes with this series of cut-and-paste activities. Offering a variety of materials from printable pattern blocks to a series of matching exercises, this resource will have your...

How is a sphere like a prism? Learners compare and contrast 3-D shapes, first drawing each in the boxes provided. If this is too advanced, supply pre-cut images of the shapes for students to choose from and glue onto the instructional...

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...

Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber bands...

This engaging presentation would be helpful for your young learners of geometry. Pupils are given clues as to what a shape may be, then they have to use those clues to guess what shape is being described. Shapes used are the circle,...

Get to know eight shapes by name: square, rectangle, triangle, pentagon, hexagon, and octagon. Young geometers write the correct name below each of these shapes, using a word bank for guidance. Then, they draw two of the...

Take your math lesson to another dimension with this lesson about 3-D shapes! First graders label cones, cylinders, pyramids, spheres, cubes, and prisms, and then count the number of each shape in a collective picture. A great way to...

Have fun with shapes! Third graders read a set of instructions and circle the shape in the description. They work on recognizing parallel sides and right sides. Use this resource as homework after your geometry lesson.

Learners will recognize these colored two-dimensional shapes and their names. The circle and all shapes with three to six sides are presented in this two-page reference sheet. With only four shapes looming large on each page, this can...

Quadrilaterals can be quirky! Fourth graders use geoboards and bands to create four-sided figures. They analyze the attributes such as angle size and presence of parallel sides. As a result they learn to differentiate among...

Expose youngsters to 3-D objects in a hands-on learning activity involving marshmallows and toothpicks. Engage your young mathematicians by introducing them to 3-D shapes by means of a story book. Explore 3-D shapes by manipulating...

Young mathematicians rotate, flip, and sort their way to an understanding of the different attributes of geometric figures. Using transparent yellow and blue shapes, children try to match congruent figures together...

This collaborative activity investigates the meaning of a trapezoid and a parallelogram. It begins by presenting two different definitions of a trapezoid. Learners are to reason abstractly the difference between the two definitions and...

Learning that size and orientation don't affect the classification of shapes is a big step for young mathematicians. Support children with developing this key understanding by looking at the array of shapes included in this resource. For...

Shapes are really neat, and here's a lesson that will help learners identify shapes through song, touch, and sight. They sing a shape song as they bounce different shapes around in a parachute. They then read a story and feel each shape...
