Understanding when to divide by two or one-half can be confusing. Here is an activity that gives four different scenarios. It is up to your number crunchers to decide if they divide by two or one-half. The easiest way to approach the exercise is to have students model each situation as shown in the commentary. Once the fraction model is complete, learners will be able to write an equation to represent the problem. This is a great problem for differentiating the division of whole numbers by two or one-half.
