Mr. Peterson's video tutorial covers fraction, decimal, and percent models. It begins with an introduction to these concepts, followed by detailed explanations of fractional parts using shaded rectangles. The video then transitions to modeling decimals, illustrating how to convert fractions to decimals. Finally, it covers percent models, explaining how to calculate percentages from fractions and grids. The tutorial emphasizes understanding through visual models and step-by-step calculations.
