I created this activity as part of a post-grad project to assess primary student misconceptions in spatial measurement of area, perimeter, circumference, surface area, and volume of shapes including cuboids, prisms and cylinders.
Students essentially calculate the various properties of a shape, which is slowly manipulated and recalculated bit by bit, with each step being more challenging than the last. Questions have been asked which relate to common misconceptions in maths and will provide insights into whether students really understand the concepts of area, perimeter, circumference, surface area and volume, and if they are able to apply what they do know to potentially real life situations.
I really enjoyed doing this activity with my primary (grade 6/year7) students and found it fascinating to see what misconceptions they had. It's worth noting, however, that the last task proved too challenging for them so perhaps it would be better suited to a grade 7/8 or year 8/9 class.
This activity will take about an hour. It comes with an answer sheet and a few notes for the teacher, highlighting misconceptions children may have.
