What does it mean for parts to be equal?

Back

Equal parts are pieces that are the same size. For example, if a pizza is cut into 4 equal slices, each slice is the same size.

Front

What is one half?

One half means that something is divided into 2 equal parts, and we have 1 of those parts.

Front

How can we tell if a shape has equal parts?

Back

We can tell if a shape has equal parts by looking at the size of each part. If all parts are the same size, they are equal.

Front

What is the numerator in a fraction?

Back

The numerator is the top number in a fraction. It tells us how many parts we have.

Front

What is the denominator in a fraction?

Back

The denominator is the bottom number in a fraction. It tells us how many equal parts the whole is divided into.

Front

If a shape is divided into 4 equal parts, what fraction does each part represent?

Back

Each part represents one fourth (1/4) of the whole shape.

Front

What does it mean if a shape is divided into unequal parts?

Back

Unequal parts are pieces that are not the same size. For example, if a cake is cut into 3 pieces, and one piece is much bigger than the others, those parts are unequal.

Front

If I have 2 out of 4 equal parts shaded, what fraction is shaded?
