Web Whiteboard - Drawing Mathematical Modes of Representations

NIE is conducting a study on how mp3 is being translated into teaching and learning practices and today my Math lesson was observed.

To conclude whether students have grasped the main concepts taught i.e. mean, median and mode (3Ms) and the various of modes of representation (e.g. dot diagram, stem and leaf), I brought in M&Ms for each student so that we work with real data.

All the information were captured via a Google Spreadsheet.



Students had to open their own packet of M&Ms and input the data into the cells. Data can thus be analysed at the group level and the class level.

The girls then worked in their groups to draw a dot diagram based on the group data and to draw another diagram using the class data. I explored getting the students to draw their diagrams using this web 2.0 tool (awwapp.com). This is a sample of the students' work. 

Students also had to find the 3Ms based on the data and input their responses into a Google Form. I then discussed what the students had done using their responses. The happiest thing I heard was this student saying that we should have more of such lessons. Well, I told her I would love to, if I had more time ;p
