Big Idea:
A percent is a part-to-whole ratio when the whole is 100.
This lesson builds on students' work in finding equivalent ratios, equivalent rates, and unit rates. In this task, students will use the percents of different colors of candy in a bag to determine the number of each color in different sized bags. Students will be presented with the percent of each color that is in a bag of LZ Choco Bits, and they will have to find the number of each color, knowing that there are 3 pink candies. In doing this, students will have to find the total number of LZ Choco Bits, and the number of each of the other 5 colors. This task builds towards a deeper understanding of what a percent means that will be necessary when students study percent change in grades 7 and 8.
Vocabulary: part-to-total ratio, percent
