Calculator Remainders
In this lesson from NCTM, students develop a deep conceptual understanding between remainders and the decimal part of quotients. They learn how remainders and group size work together to influence the results that are displayed on a calculator. Students use beans to physically represent quotients that have remainders, and they compare remainders written as fractions of whole groups to the results obtained with a calculator.

Big Math and Fries
We are lucky to live in an age where there is a lot of nutrition information available for the food we eat. The problem is that much of the data is expressed in percents and some of those percents can be misleading. This lesson is designed to enlighten students about how to calculate percent of calories from fat, carbohydrates, and protein. The calculations are made to determine if a person can follow the Zone Diet with only McDonald's food items.

6th Grade Dividing Fractions
In this lesson from Engage NY, students use visual models such as fraction bars, number lines, and area models to show the quotient of whole numbers and fractions. Students use the models to show the connection between those models and the multiplication of fractions.
Students divide a fraction by a whole number.
