: Calculating the perimeter of shapes (triangles/rectangles) and drawing line segments of specific lengths.
: 2–3 gross errors or a higher volume of minor mistakes, provided the solution logic is generally correct. "2" (Fail) : More than 4 gross errors. Preparation Resources
: 1 "gross" error (major conceptual mistake) and 1–2 minor slips are allowed.
According to standard Methodological Recommendations , results are evaluated as follows:
: Using "convenient ways" to calculate sums (e.g., grouping numbers like to find sums of 10 or 20 first).
