On Friday we wrapped up our unit on data collection. Some of the major learning goals for students included

During one of the last activities, students had to measure how far they could jump.  Students worked together with a partner to measure the distance of their freestanding jumps.  We then collected and organized the data and compiled it into a quick plot line.  Students then worked on answering the following question.

Based on the data from our class, what could we tell someone is a typical distance for a Grade 3 student to jump?

Please continue reading to see some of the highlights of our discussion which I think demonstrate learning various students did around the idea of analyzing data and looking at data as a whole rather than just picking out individual data points on a graph.

Green circles - “The typical jump would be 52 or 55 because those are the most popular lengths.”
Orange circle - “The typical jump would be between 52 and 55 because there seems to be a clump of data there.”
Turquoise circle - “The typical jump would be between 55 and 58 because every value between those two numbers has at least one student and 55 has two students.”
Blue circle - “The typical jump would be between 48 and 58 because the data is very spread out but that is where the main clump of data is, except for some outliers.”
