Exploring Equal Parts in 3rd Grade Math

The video tutorial covers lesson five, part two, focusing on fractions as equal parts. It begins with an introduction to the materials needed, such as whiteboards and fraction pieces. The lesson includes calculating the area and perimeter of rectangles, followed by finding the area of irregular shapes by dividing them into rectangles. The tutorial then shifts to using fraction circles to explore parts of a whole, with exercises to identify fractions of different colored pieces. The session concludes with instructions to upload completed work to Schoology.
