This is a file created using Senteo Notebook software that can be used with Senteo Voters. However, the file can also be used the old fashioned way and printed out if you don't have Senteo. The lesson was created to help students in first and second grades learn the geometrical shapes of a cone, sphere, cube, and rectangular prism (cuboid). The lesson contains 12 different slides showing twelve different examples of these 3-D shapes. The preview shows a brief example of what you are getting with this lesson. For all who purchase this lesson, I wish you the best while teaching these concepts.
