The document describes a web-based tutorial for teaching place value concepts to 3rd, 4th, and 5th grade students. The tutorial consists of 15 slides that use graphics, animations, text, and audio narration to define place value, explain the place value system for whole numbers and decimals, demonstrate how to read and write numbers using place value, and provide practice questions for students to assess their understanding. The goal is for students to learn and review place value independently using the online resource.
