8th Grade Math Assessment Practice: Key Concepts and Strategies

This video tutorial covers various eighth-grade math topics, including decimal place value, probability calculations with examples like a fruit basket and a restaurant menu, and probability with a cube and spinner. It also explains how to convert model airplane measurements to actual size and how to match inequalities with graphs. The session is designed to enhance understanding of these concepts through practical examples and problem-solving techniques.
