How accurately could you estimate the number of sheep in a field without counting them? If there were only five sheep in the field your estimate would probably be very accurate but if there were fifty how close do you think your estimate might be? In the first case your estimate would have probably been perfect while in the second case you are unlikely to get it absolutely correct. What is the cut off number, between five and fifty where your estimate starts to become less accurate?

Have you ever tried herding sheep? Not easy is it? The online herding sheep activity is much easier than real life herding and has proved to be a great introduction to loci.
