Reading, Mathematics, and Science Questions The Reading, Mathematics, and Science Questions include an introduction, 17 reading units, 50 mathematic units, and 34 science units released from the 2000, 2003, and 2006 PISA assessments. The assessments focuses on students' abilities to use their knowledge and skills to meet real-life challenges, rather than merely on the extent to which they have mastered a specific school curriculum. This task includes:

Reconstruction Riots This task requires students to weigh the values and limitations of a document as historical evidence on the topic of Reconstruction. Students with a sophisticated understanding of how to source a document will be able to explain that the primary source illustrations (Harper's Weekly, 1866) might be useful because they were contemporary depictions of the riots. They will also observe, however, that the artist may not have been present at the riots- and that this is a rendition drawn either from memory or from others' accounts, making it less useful as evidence of what happened. Resources include PDF downloads of the assessment with source materials, and a rubric with benchmark descriptors. |

Regional Ratios In Regional Ratios, students find the ratio of the area of a hexagon to that of an equilateral triangle when the perimeters of the two figures are the same. It might be solved by directly calculating the areas using shape-specific area formulas, calculating the areas using the Pythagorean theorem or the properties of 30-60-90 right triangles, or by dissecting the shapes into smaller equilateral triangles. This task includes:
