I’ve been doing research on the Trends in International Mathematics and Science Study (TIMSS) lately and came across this sample 8th grade question (source):
PQRSTU is a regular hexagon. What is the measure of the angle QUS?
All the other questions (including the 4th grade ones) seem reasonable (easier than I expected, even) but is this one really an 8th grade question? Even my current geometry students would have difficulty. I don’t recall ever getting anywhere past area and perimeter in middle school; is the TIMSS expecting a full geometry class by 8th grade, so algebra would be taken 7th grade? I imagine the majority of students could still solve this problem by eyeballing the figure and guessing, but that hardly seems the intent of the question.
