Conducting activities in groups provides the teacher with the opportunity to allow students to mingle with each other, at the same time giving them the chance to learn from each other. In Differentiated Learning there are many ways to group students.
One of the ways to group students for specific activities is Flexible Grouping. In this particular example where the teacher is teaching about the topic of 'Old and New Machines', students are grouped according to Similar Interest groups.
Instead of numbering students accordingly to form groups of four or five, teacher randomly assigns different tools to students and then get them to get together in the groups based on the names of tools given to them earlier (see picture above)
This particular topic also allows the teacher to encourage students to further use I-Think Maps in the lesson, this this case using the Double-Bubble Map (see picture above) Using this particular type of I-Think Map plus the Flexible grouping allows students of different abilities to discuss and learn from each other and also to develop their roles both as a group and as an individual.
