The Component Addition Concept Builder is comprised of nine problems in which two or more vectors must be added in order to determine the magnitude and direction of the resultant. Each problem is scaffolded and directed so that students gain the sense of how resultants can be determined from their compoents. There are three levels of difficulty with three different problems per level. Those three difficulty levels are differentiated as follows:

• Apprentice Level: Question Groups 1-3; add 2 vectors
• Masters Level: Question Groups 4-6; add 3 vectors
• Wizard Level: Question Groups 7-9; add 4 vectors

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 might be profitable for a student to complete the Concept Builder at the Apprentice Level in order to gain some confidence and then to be challenged to complete the activity at the Masters Level.
