Display the €0.50 shelf tag beside one half of a shaded bar as pupils settle. Take three hands-up answers, not open call-outs. Listen for both one half and zero point five — if only one comes up, revoice: so it has two names, a fraction name and a decimal name.

Half strip: 5 of 10 shaded, one half is 0.5. Point to the five parts and the readout together. Introduce the phrase decimal twin for later.

One tenth: 1 of 10 shaded, 0.1. Pause and ask the class to predict two tenths before moving on.

Three tenths: 3 of 10 shaded, 0.3. Link the shaded count to the single digit after the point; note the length grew each time.

Quarter: before revealing, ask more or less than one tenth. Let the tenths pattern settle first.

Then reveal the hundredths strip: 100 parts, each one hundredth, smaller than a tenth. A quarter of a hundred is 25, so 25 hundredths shaded. Point along them so pupils see why a quarter needs two places, 0.25.

Tie to money: a quarter of a euro is 25c, €0.25.

This quarter step is the make-or-break moment, don't rush it.

This round is for talking it through together — pupils take turns at the board and the class agrees or corrects out loud.

For each one, ask the pupil at the board to shade the strip, then read both names — the fraction and the decimal — before the class confirms. The first three use the tenths strip. For the quarter, switch to the hundredths strip so the picture matches: pupils shade twenty-five of a hundred parts. Revoice: a quarter is not a tidy number of tenths, so on the hundredths strip it lands on twenty-five hundredths, 0.25, with two places. Rotate four pupils; keep it brisk.

These are the practice questions — pupils take turns at the board, check each answer, and the class confirms before moving on. Keep the board work brisk rather than over-explaining.

The challenge builds from the tidy tenths (0.5, 0.1) to the quarters (0.25, 0.75), shown on the hundredths strip where two places are needed. The point is three quarters landing on 0.75 — ask the class to predict the decimal before the pupil shades it. Watch for pupils shading only three parts for three quarters; revoice with the seventy-five hundredths on the hundredths strip.
