Pick the group that this shape
belongs to.
We’re given a picture of a
rectangle, and our question asks us to pick the group that this shape belongs
to. Underneath the picture, we can see
the two groups that we’re talking about. One is labeled equal parts and the
other is labeled unequal parts. The word both these groups have in
common is the word “parts.” Both groups contain shapes that
have been split into different pieces or parts. They both contain orange
rectangles, and they both contain green circles. If we count the number of parts
that each of the rectangles have been split in to, we can see that they’ve both been
split into two parts.
But what’s the difference? Have they both been split in the
same way? The parts in the first rectangle
are the same size. They are equal parts. But if we look carefully at the
rectangle in our second group, we can see that the parts are not the same size. They are unequal parts. Now, we’re beginning to understand
what each group shows. The circle in this group has been
divided into four parts and they’re all the same size. The circle in the second group has
also been divided into four parts, but they’re not all the same size.
Let’s go back to look at our pink
rectangle. Are the parts that this rectangle’s
been split into the same size? It’s been split into three parts,
hasn’t it? And when we look at them, they do
look the same size. They are equal parts. The shape has been divided fairly
into parts or pieces that are all the same size. It belongs in the group of shapes
with equal parts.
