We can sort these objects into categories. Which of the following categories have the objects been sorted by? Size, colour, or shape.
We’re shown some pictures of different objects. And the objects have been sorted into different groups or categories. The question is asking us which category was used to sort the objects. Have the objects been sorted by size, by colour, or by shape?
Let’s look more closely at how the objects have been grouped. Let’s start by looking at group one. It has a green car, a green boat, and a green plane. All of these objects are the same colour. They’re all green. In the second group, all of the objects are red. A red boat, a red train, and a red car. All of the objects in group three are the same colour. The train, the car, and the pram. So we can say that all of the objects have been sorted by colour. The category used to sort the objects is colour.
