My Time-Estimation Experiment
Choose real or fictional examples. Skip private details; never include passwords, medical information or contact details.
Learning goal: Compare predicted and actual task time to improve a future estimate.
Time estimates are experiments, not promises. A task can take longer because you needed materials, learned something new or were interrupted. Test a few tiny tasks and use the evidence to plan, without turning speed into a measure of worth.
- Pick three short, safe tasks you can try within this session.
- Predict minutes before each task.
- Measure actual time with a clock or adult cue.
- Compare results and adjust one future estimate.
1. Predict, then measure
Pick tasks of about 1–3 minutes each. Include getting ready in the actual time.
Example: collect materials · predict 2 · actual 3 · 1 minute longer.
| Task | Predicted min | Actual min | Difference |
|---|---|---|---|
| 1 | |||
| 2 | |||
| 3 |
2. Explain the evidence
A difference is information. Think about what happened, not whether you were “fast enough.”

3. Plan the next experiment
Use your evidence to set a realistic estimate and buffer.
| Next task | New estimate | Buffer | What I will check |
|---|---|---|---|

| A similar future task |
My next step
Next time I estimate, I will remember to include…
Optional stretch · Grades 6–8
Separate setup time from working time. Compare repeated trials and explain why a single measurement may mislead.
