Students came back to school well rested and full of enthusiasm for the second half of the year. After sharing stories from the holidays-skiing trips, movies, ice skating, play dates and trips to Grandma’s house- we set about investigating a new strand of mathematics.
Central Idea
Range, mode, median and mean can be used to analyse statistical data
The following questions are being used to guide students through this investigation:
How can we manipulate data?
How can we interpret data?
How can we present our data effectively?
As a getting started activity, students explored the power and versatility of graphs by looking at Hans Roslings' graph of 200 countries over 200 years. Students pondered the question, "Was this data presented effectively?" You can visit the interactive graph here.
To construct meaning, student were asked to investigate the following question:
Do you have good balance?
As a class, we brainstormed the different aspects of data handling:
Planning
Collecting data
Recording data
Organising data
Analysing data
Presenting data
Students worked their way through this investigation, pausing along the way to learn different methods of organising data and to practice calculating landmarks to help analyse the data. Finally, students used the collection of data to answer the question. Of course they used the landmarks to help justify their answer. Students experimented with different graphing options to best present the data and highlight the answer to the question.
Here are some students working through the investigation.

I am curious about how they organized their data and how their graphing experimentation looked like.
ReplyDeleteA few students will be demonstrating how they worked through that question at the next parent sharing session on Tuesday. The more important question is, "Do you, Ms Naini have good balance?" And, can you back it up with data?
