Linking Simple Fractions and Decimals

Explore how common fractions like one half and one quarter match up with their decimal twins (0.5 and 0.25). Use shaded strips to see why tenths convert straight across, and spot these patterns in real shopping prices.

    1 - Getting Started ~4 mins

    Illustration for Getting Started

    Key point

    Here is a shelf tag showing half a euro. We can call this same amount two different names. What are the two names? One is a fraction, one is a decimal. Have a think, and get ready to say both out loud.

    👇 Mark your steps as done as you complete them.

    +5 XP

    2 - Watch and Notice ~9 mins

    The interactive shows shaded strips, each with its fraction name and its decimal readout. Watch how the shaded length changes and see the two names for the same amount. Be ready to predict the next decimal before it appears.

    👇 Mark your steps as done as you complete them.

    3 - Try It Together ~9 mins

    Key point

    Today we shade the strip and read off its decimal twin together. We work through these in order: first one half, then three tenths, then seven tenths on the tenths strip. Then we move to the hundredths strip for one quarter.

    Watch out

    The quarter is the tricky one, so we will say its two decimal places aloud and count the twenty-five hundredths before we check it.

    Shade the fraction, read the decimal

    4 - Write the Matching Pairs in Your Copy ~2 mins

    COPYBOOK MOMENT

    In your maths copy, write these three matching pairs, one under the other:

    • one half = 0.5
    • one quarter = 0.25
    • three tenths = 0.3

    Then pick one pair and draw a quick bar to shade and check it.

    5 - Class Challenge ~8 mins

    Key point

    Today we shade each strip to match the decimal on the card, then check. We work through these in order: one half, then one tenth, then one quarter, and finally three quarters. The last two use the hundredths strip, so watch the hundredths carefully.

    Match the fraction to its decimal twin
