Supplied materials
- Paper or a text document; all cases below are original fictional learning inputs.
- An adult may read aloud; drawing or spoken answers are valid. No personal health information or physical performance is required.
- The separate worked case gives bedtime 24 h=21, wakeHour=6. Calculate 24−evening bedtime+next morning wake hour. First identify the quantities and keep their units consistent. The calculation is 24-21+6=9 hours opportunity. Round to six decimal places where needed. That result answers this supplied planning question only. It does not establish what a real person did, diagnose a condition or prove physical skill. Compare the units with the question before accepting a number.

- Fictional case 3: bedtime 24 h=23, wakeHour=7. What is the modeled result using the stated method?
- Fictional case 4: bedtime 24 h=21.5, wakeHour=6.5. What is the modeled result using the stated method?
- Fictional case 5: bedtime 24 h=23.5, wakeHour=6. What is the modeled result using the stated method?

Learn the idea
Teens ages thirteen to eighteen generally need eight to ten hours of sleep per day. This lesson uses a fictional seventeen-year-old. Available overnight time is a planning window, not proof of actual sleep or a personal sleep prescription.
Count from evening bedtime to midnight and then to the next morning wake time. Use decimal hours for half-hours. A later obligation can reduce opportunity even when the wake time stays fixed. Do not treat the difference as a measured medical condition.
All schedules are invented. No sleep diary, symptom inventory, supplement or medication plan is required. Actual ongoing sleep concerns need caregiver and qualified support. The task teaches time budgeting and honest evidence limits.
- Mark the facts or constraints in the supplied case.
- Apply the method explained above; draw a sequence, table or decision map.
- Compare your result with the worked solution and explain the difference.
- Complete the new cases, then check the changed-case extension.

Helpful tips
- This fictional 17 year-old uses 13–18 guidance; grade alone is not the age.
- Time reserved is not time actually asleep, and no diagnosis follows.

9 hours opportunity
Calculate 24−evening bedtime+next morning wake hour. With bedtime 24 h=22, wakeHour=7, calculate 24-22+7=9 hours opportunity. Results are rounded to six decimal places where needed. This is a supplied model, not a personal health assessment.
Take it further
Changed case: bedtime 24 h=22.5, wakeHour=7. Show the operation. Expected: 24-22.5+7=8.5 hours opportunity; round to six decimal places where needed, retain model limits and explain the units.
