3.form student groups ( mock machine shop) 


B. Development
1.review print for a different part
2.key points for production
3.cost of production

C. Practice
1.students work through scenario with instructor as a class to estimate
cost on a similar part
2.questions and discussion afterwards
3.students are placed in their groups 


D. Independent Practice
1.students estimate time for simple machine operations
2.actual time is compared to students estimated time
3.questions and discussion afterwards 


E. Accommodations (Differentiated Instruction)

2.power point presentation at class beginning
3.prior reading assignment 


F. Checking for understanding
