Naming and Writing Fractions

Let's get practical with fractions! This topic introduces children to naming and writing common fractions by connecting words, symbols, and pictures.

Activity 01

Stations Rotation20 min · Small Groups

Fraction Pizza Party

Give each group a paper plate 'pizza'. Call out a fraction, like 'one quarter', and have the children draw lines to divide their pizza into the correct number of equal slices and then shade in the fraction.

Explain the relationship between the name 'one quarter' and the fraction 1/4.

Facilitation TipUse pre-cut circles to ensure accuracy and focus the activity on dividing and shading, not on drawing.

What to look forUse mini whiteboards. Show the class a shape with a fraction shaded (e.g., 1/4 of a square) and ask them to write down the fraction. This gives an instant check for understanding.

Fraction Wall Build

Using strips of coloured paper of the same length, children create their own fraction wall. They start with a 'whole' strip, then fold and cut other strips to make halves, quarters, and eighths, labelling each piece.

Identify the fractions represented by various shaded diagrams.

Facilitation TipEncourage children to talk about what they notice, for example, that two quarters are the same length as one half.

What to look forObserve children during a practical activity, like building a fraction wall. Listen to their mathematical language and note any misconceptions as they discuss their work with a partner.

Fraction Match-Up

Create a set of cards with fraction names (e.g., 'one half'), symbols (1/2), and pictorial representations (a shape shaded in). Children work in pairs to match the three corresponding cards.

Compare the written form of 'one half' and 'one eighth' and explain which represents a larger piece.

Facilitation TipStart with only halves and quarters before introducing eighths and tenths to build confidence.

What to look forProvide a short worksheet at the end of the topic. Include tasks like matching fraction names to symbols, writing the fraction for a shaded shape, and shading a shape to represent a given fraction.

A few notes on teaching this unit

Start with concrete materials every time. Use paper folding or sharing objects to introduce each new fraction before showing the written symbol. Constantly ask, 'How many equal parts make the whole?' to reinforce the meaning of the denominator. Move to drawing and shading fractions in their copybooks only after they have had plenty of hands-on practice.

By the end of these activities, your pupils will be able to confidently read, write, and identify halves, quarters, eighths, and tenths.


Watch Out for These Misconceptions

  • A student believes that 1/8 is larger than 1/4 because the number 8 is larger than the number 4.

    Use a concrete example, like a bar of chocolate. Show that when you share it among 8 people (eighths), each person gets a much smaller piece than if you share it among only 4 people (quarters). Emphasise that the denominator tells us how many pieces we are sharing between, so the more people, the smaller the piece.

  • A student reads 1/4 as 'one and four' or 'one over four' without understanding its name as 'one quarter'.

    Consistently model the correct language: 'one quarter', 'one half', 'one eighth'. Connect the word 'quarter' to other familiar concepts, like a quarter of an hour on the clock or four quarters in a euro.

  • A student thinks that any two pieces of a shape make a half, even if they are not equal in size.

    Stress the term 'equal parts'. Use activities like paper folding to demonstrate that for a fraction to be a half, the two parts must be exactly the same size. Compare a correctly folded half with an unequally divided piece of paper.
