Answer 3

Start by looking at all your pictures (animals or what ever). Pick one major trait that you can separate them into 2 distinct groups. When you have done this write down the trait in the form of a question. Example: 1A. All animals contain 4 legs. Go to 2A.
1B. Animals do not contain 4 legs Go to 4A.

Now you look at both groups and find a trait the will divide the groups into 2 more subgroups.

Example: 2A. All animals contain hair Go to 3A.
2B. All animals contain feathers ...... Birds.

Continue until you get all your animals or objects listed.

Look at a key and see how it is set up. It is based on opposites.
