Figure 3
The photograph shows handwritten notes on paper containing small sketches and arithmetic calculations. In the first row on the left, the circular shape within two small circular shapes is drawn. The three larger circular shapes, with text above the circles reading “1 Hr”, and“n n n”. To the right of these drawings appears the equation “ equals 54 kr”. Further to the right is the expression “54 minus 12 minus 12 minus 12 equals 18 kr”, and on the far right, the expression “18 divided by 2 equals 9 kr”. In the second row, four small bottle-like shapes are drawn in sequence, followed by the equation “equals 60 kr”. To the right appears the calculation “60 divided by 4 equals 15”. In the third row, two bottle-like shapes are drawn, followed by a circular shape. To the right of the drawings appears the equation “equals 42 kr”. Further to the right is the calculation “42 minus 15 minus 15 equals 12 kr”.Drawing visualisation (Group 4)
