Sure, let's keep it simple:

1. Oranges: Oranges are the big, round fruits you often see. They can be sweet or a bit tart. You have to peel them to eat them, and they usually have several juicy segments inside.

2. Tangerines: Tangerines are smaller and sweeter than oranges. They're also round, but they're easier to peel. They have a lovely, sweet flavor and are often enjoyed as a snack.

3. Satsumas: Satsumas are a type of tangerine. They are even smaller and very easy to peel. They are often very sweet and have a slightly loose skin, making them super convenient to eat.

4. Easy Peelers: "Easy peelers" is a term used for any small citrus fruits that are easy to peel. This can include tangerines, satsumas, and other similar fruits. They are called "easy peelers" because you can quickly and easily remove the skin with your fingers, making them a great on-the-go snack.

So, while oranges, tangerines, satsumas, and easy peelers are all citrus fruits, they vary in size, sweetness, and how easy they are to peel.
