On Friday we wrapped up our unit on data collection. Some of the major learning goals for students included
- describing the shape of ordered, numerical data
- developing arguments based on data
- describing what values are typical or atypical in a data set
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.

Our class just finished their first data analysis project.
Step One: Formulate a question.
Students worked in groups and then as a class to formulate a clear question. The final question was Is your favorite pet a dog, a cat, a rodent, a reptile, a bird or a fish?
Step Two: Collect the data
Students went in small groups to collect data from a class in kindergarten, grade 1, grade 2, grade 4, grade 5 and we answered the question ourselves to represent grade 3.
Step Three: Organize the data
Students then looked at the results of the survey groups and reorganized the data to answer the following question. Is your favorite pet a mammal, fish, bird, reptile or insect?
Step Four: Display the data
Students used Excel to create electronic graphs and to experiment with different kinds of graphs that could best display the results. Then they created graphs displaying the data from two of the survey groups.
Step Five: Analyze the data
Students worked with their groups to make observations that compared the data as a whole, using words such as most, few, more than half, less than half, almost all.
They also recorded some reflections on what made graphs clear and easy to read and what made other graphs harder to interpret.
Watch the children reflect on their learning.
