Work Hours and Weekly Pay Activity
A 35–45 minute adult numeracy activity to check a weekly timesheet, convert hours and minutes to decimals, and estimate gross pay.
Figur Editorial · Reusable practical numeracy activities for educators · 2026-09-13
Audience and learning objective
Audience: adult basic education, workforce preparation, high school equivalency, or community education learners who can add and multiply whole numbers and are beginning elapsed-time and decimal work.
Objective: learners will calculate paid time after an unpaid break, explain why 7 hours 30 minutes equals 7.5 hours rather than 7.3, and estimate weekly gross pay from an hourly rate. Allow 35–45 minutes. Materials: an internet-connected device, paper or notes app, and the scenario below.
Activity steps
Scenario: Jordan earns $18.40 per hour. Monday and Tuesday: 8:15 a.m.–4:45 p.m., 30-minute unpaid break. Wednesday: 9:00 a.m.–5:15 p.m., 45-minute break. Thursday: 8:30 a.m.–4:30 p.m., 30-minute break. Friday: 8:00 a.m.–2:30 p.m., no unpaid break.
- Estimate whether Jordan worked more or less than 40 paid hours. Record the estimate and reasoning.
- Use Work Hours for each day. Record paid time in hours and minutes and decimal hours.
- Add the five decimal results and multiply by $18.40 for estimated gross weekly pay.
- Check with Hourly to Salary using the weekly hours and 52 working weeks.
- Change Friday's end to 5:00 p.m. Compare the added time and pay. Do not add overtime unless the educator supplies a specific rule.
- In pairs, explain differences caused by minute conversion, break subtraction, or early rounding.
Discussion questions
Use these for whole-group discussion or written reflection.
- Why is 30 minutes 0.5 hour? What fractions of an hour are 15 and 45 minutes?
- When is it safest to round, and how can early rounding affect weekly pay?
- What details on a timesheet or pay stub would help check the estimate?
- Why can take-home pay differ from gross pay when hours and rate are correct?
- How would an overnight shift or paid break change the inputs?
Accessibility and teaching notes
The activity supports keyboard and screen-reader use. Provide selectable digital text, read the scenario aloud, allow a 24-hour clock, and accept spoken, typed, handwritten, or calculator-supported work.
Do not require learners to disclose their wage, employer, schedule, or pay stub. Use the fictional scenario and allow extra time for learners new to clock notation or decimal multiplication.
Calculator assumptions and answer check
Work Hours subtracts the entered unpaid break. Hourly to Salary multiplies hourly rate, weekly hours, and working weeks. Results exclude taxes, benefits, paid leave, differentials, payroll rounding, and overtime rules.
Answer check: 8.0 + 8.0 + 7.5 + 7.5 + 6.5 = 37.5 hours; gross weekly pay is $690.00 and 52-week gross is $35,880.00. With Friday ending at 5:00 p.m., total time is 40.0 hours and gross pay is $736.00.
These are educational estimates, not payroll, tax, employment, or legal advice. Workplace policy and applicable law determine paid time and overtime.
