Discuss with your friends and teacher the strategies you could use when estimating a distance.
Extension activities:
Copy and paste your table of results into a spreadsheet then investigate the following:
- What is the average time it took you to make your estimate?
- Is your estimate more likely to be higher or lower than the actual distance?
- Is there a correlation between the distance and your percentage error?
- Can you work out the formula the computer uses to calculate your score?
- Can you get better at estimating with practice?
