There are a huge variety of animals. We can start to understand this variety by looking at one characteristic (one part of it). The first characteristic we’ll look at is legs.
Open up the number line.
Put each animal or picture next to the number of legs it has. If you are not sure, don’t guess - look closely and you might have a better idea of the answer. Scientists often look closely to learn more about something. All the animals fit on this number line. [Worm 0, snake 0, human 2, mammal (usually) 4, wood bug 14].
