Figure 4
The composite photograph contains two separate visual problem-solving diagrams placed side by side. On the left, a hand-drawn scale diagram shows three horizontal line segments labeled “STÖRST”, “MELLERST”, and “MINST”. The top line labeled “STÖRST” contains a single tick mark near its center. The middle line labeled “MELLERST” contains two tick marks along the line. The bottom line labeled “MINST” is the longest and contains several evenly spaced tick marks along its length. Below the lines, the number “120” is written. On the right side, a colored block model diagram is shown with three rows labeled “M”, “B”, and “S”. Next to “M” is a single rectangular block. Next to “B” is a shorter rectangular block labeled “negative 32”. Next to “S” are three equal rectangular blocks placed side by side. Below these rows appears a longer bar composed of several connected rectangular segments followed by a smaller segment at the end. To the right of this bar the expression reads “equals 782”. Further to the right, the calculation reads “782 divided by 5”.Line and area visualisations (Groups 1 and 3)
