Younger students have much to learn from older ones, and vice versa!
Younger students learn more maturity from older students.  Older students solidify and strengthen their knowledge of a topic when they help teach it to younger students.  Older students learn how to be patient and compassionate when younger students exhibit less mature behaviors Differences of age and experience add to the diversity of the classroom, and all learn from each other Age diversity is more reflective of the environments children will be in “in real life” when they are older and enter the work force Working with different age groups and abilities fosters more dynamic cooperative skills The class feels more like a family (“we learn from and listen to each other, we’re all in this together”), than a factory floor (“we are all puny underlings who have to produce according to the boss’s standards”)
