reSolve: Authentic Problems: Reaction Time

This sequence of four lessons focuses on collecting data and working with decimal numbers in the context of students measuring reaction times. Students formulate and refine an authentic inquiry question related to their own statistical investigation, and plan how to investigate it. They compare and order decimals that represent very fast and precise reaction times. They construct data displays, including dot plots, appropriate for the data, and justify their conclusions. Each lesson is outlined in detail including curriculum links, vocabulary, materials needed, sample answers, discussion points and student resources. This sequence is part of the reSolve: Mathematics by Inquiry special topic 'Authentic Problems'.
