There are three levels of difficulty by which the student can progress through the Concept Builder. Those three difficulty levels are differentiated as follows:

**Apprentice Level**: Groups 1-4**Masters Level**: Groups 1-8**Wizard Level**: Groups 1-12

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which level of difficulty is most appropriate for their classes. We recommend providing students two or more options. For instance, it would be profitable for a student to complete the Concept Builder at the
