Continuum of Activities
The list below represents a continuum of activities: resources categorized by Standard/Eligible Content that teachers may use to move students toward proficiency. Using LEA curriculum and available materials and resources, teachers can customize the activity statements/questions for classroom use.
This continuum of activities offers:
- Instructional activities designed to be integrated into planned lessons
- Questions/activities that grow in complexity
- Opportunities for differentiation for each student’s level of performance

Activities
- What is system input?
- What is system output?
- What is system feedback?
- How are the system input and the system output related?
- What role does feedback play in an open-looped system? In a closed-looped system?
- Name 2 systems you use regularly that do not monitor feedback. How would your life be easier if these systems monitored feedback? Explain your thinking.
Answer Key/Rubric
- System input is the information that is sent to and received by the processing system.
- System output is the information that the processing system sends to another system.
- System feedback is information that an output system gives back to the input system. The input system is then able to make adjustments based on the feedback if necessary.
- Acceptable responses may include, but are not limited to:
- Input is the information that is given to a system.
- Output is the information that a system sends to another system.
- The information that is output by the system depends on the action the input told the processing system to perform.
- Acceptable responses may include, but are not limited to:
- An open-looped system does not monitor its output through feedback.
- An open-looped system performs that action assigned by the input system, but does not adjust for any errors in the output.
- A closed-looped system monitors its output through feedback.
- Feedback is sent back to the input system and sent through the processing system again.
- The processing system is able to make adjustments based on the feedback.
- Closed-looped systems are able to monitor their output in order to achieve the desired output.
- Acceptable responses may include, but are not limited to:
- Clothes dryer: The dryer has time settings and will stay for the allotted time. If the dryer had a moisture sensor to detect when the clothing was dry, then I would save on energy costs because the dryer would turn off when all of the clothing was dry.
- Microwave: The microwave has time settings. It would make my life easier if the microwave had temperature sensors. Then I would not need to guess how long my food would need to sit in the microwave until it was hot. I could also choose the temperature I would like my food so I wouldn’t overestimate and burn my mouth on food that is too hot.
