## Fractions of a shape (Year 2)

Back In Year 2, we have been learning to recognise half, quarter or three quarters of a shape as well as find a fraction of a number or an amount. When we write a fraction, there is a numerator and a denominator The numerator is the number of parts we are thinking about; for example, the number of parts shaded or the number of parts missing. The denominator is the number of parts in total. Remember, just because the denominator is a bigger number, it does not mean it is a bigger fraction. For example, 1/4 is not bigger than 1/2 because 4 is a bigger number than 2.

Look at the examples below. How many parts have the shapes been split into? The answer will be the denominator in your fraction. Recognising equal parts

When you start exploring fractions, it is important that you recognise equal and unequal parts.

Look at the pictures below.

• What is the whole? What are the parts?
• How many parts is the shape split into?
• Are all the parts equal? How do you know?
• Is there more than one way to split the shape into equal parts? Half

When you divide a shape into two equal parts, each part is called a half. Two halves make a whole. In the fraction 1/2, 1 represents the number of parts shaded and the 2 represents the total number of parts.

Look at the shapes below.

• How many equal parts has the shape been split into?
• Which pictures show 1/2? Challenge 1 Challenge 2

Miss Coverdale says the shaded parts of the shape do not show a half because there are 4 parts and not 2 equal parts. Do you agree? Explain why. Quarters

When you divide a shape into four equal parts, each part is called a quarter. Remember, four quarters make a whole.

Look at the shapes below.

• Which shapes do not have a quarter shaded? How do you know?
• Can you draw the shapes again and split them into quarters correctly? Challenge 1 Challenge 2

Using two identical strips of paper, what happens when you fold the strips into two equal parts and four equal parts? What do you notice? Challenge 3

Using what you know about the numerator and the denominator, can you colour in 3/4 of each shape? Remember, the numerator is the number of parts we are thinking about; for example, 3 parts that are shaded.
