    Your turn
    Your teacher is running this lesson on the board. Here is the part you can try yourself.
    Coin counter

    1 - Getting Started ~4 mins

    CORNER SHOP
    Sandwich€5.00
    Juice€7.5
    TOTAL€12.50

    Illustration for Getting StartedHere is the receipt. The total is €12.50. Look at the price printed for the juice: €7.5. Is that written correctly for money? What is missing?

    2 - Watch and Notice ~10 mins

    Watch three money ideas build in the coin tray, one at a time.

    A zero that holds a place. In €7.50, the zero in the one-cent column keeps the 5 in the ten-cent place. Read it aloud.

    Adding money. Here are the two amounts we will add: €12.50 and €8.75.

    Now the total, €21.25. Watch what happens when a cent column goes past nine and we carry into the next column.

    Sharing money. We split €27.60 equally among three, sharing the euros first, then the cent, to reach €9.20 each.

    3 - Try It Together ~11 mins

    Today we build and combine money on the tray, one task at a time. Say each cent column aloud before we check it.

    • First, build €3.05. Watch the zero holding the ten-cent column.
    • Next, build €3.25, then work out four lots of it altogether.
    • Last, build €20.00 and count up from €13.45 to find the change.

    Build and combine money amounts

    4 - Set It Out in Your Copy ~3 mins

    COPYBOOK MOMENT

    Illustration for Set It Out in Your CopyFirst we set two sums out together on the board so you can see how money is written in columns. Watch €12.50 + €8.75 with the decimal points one under the other, then worked down each column from the right. Next watch €27.60 ÷ 3 set out the same way: point under point, short division across the euros then the cent, and the answer written as €9.20. After that, set out each calculation below in your maths copy the same way. Write every answer in standard €X.XX form and circle the cent digits on every answer.

    • €12.50 + €8.75
    • €3.25 × 4
    • €20.00 − €13.45
    • €27.60 ÷ 3
