Calculating Percentages and Attendance

Mrs. Nelson teaches a sixth-grade math lesson on finding percentages. The lesson involves calculating attendance at various school events using percentages. The video demonstrates how to use division and multiplication to find percentages of given numbers, such as determining 30%, 44%, and 140% of a concert's attendance. The lesson emphasizes using a unit rate table to simplify calculations and corrects a mistake in decimal placement during the process.
