The students will review solid figures using a baggie of assorted snack mix (cones, cubes, cylinders, and spheres) and will begin a vertical bar graph showing the number of each solid figure in a bag of assorted snack mix.
In this video segment from Cyberchase, two friends make rock candy while learning about 2-D and 3-D shapes.
Students review geometric terms by making predictions about what the Greedy Triangle will become as the teacher reads the book, "The Greedy Triangle". Students will create geometric creatures after the review.
Worksheet containing six multiple choice questions about 2D shapes.
This lesson plan is designed to use quilts as a visual prompt to review mathematics vocabulary associated with geometry in the third grade curriculum. A hands-on activity serves as a practice and review at the conclusion of this lesson.
A challenging crossword designed for children who have mastered the concepts involved in shape and space. a good knowledge of the terminology involved is required.
In this exercise you will name triangles.
Worksheet with six multiple choice questions about three-dimensional shapes such as cubes, cuboids, cones, etc.
Worksheet containing multiple choice questions about triangles
These hands-on activities make learning about geometric shapes more appealing to students.
An interactive applet and associated web page that demonstrate the properties of a cube. A 3-D cube is shown in the applet which can be interactively manipulated using the mouse. Research has shown that some younger students have difficulty visualizing the parts of a 3D object that are hidden. To help with this, the student can rotate the cube in any axis simply by dragging it with the mouse. It can also be 'exploded' - where a slider gradually separates the faces to reveal the ones behind. The cube can also be made translucent so you see through it to the other side. Applet can be enlarged to full screen size for use with a classroom projector, and printed to make handouts. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
