Exploring 3rd Grade Math Concepts in Unit 10, Lesson 13

The video tutorial covers the concepts of area and perimeter. It begins with an introduction and objectives, followed by detailed explanations of perimeter and area, including their formulas and how to calculate them. The teacher provides example problems for both concepts, demonstrating the calculations step-by-step. The lesson concludes with instructions for independent practice on pages 111 and 112 of the student journal.
