however, large class sizes have the advantage of giving children more opportunities to learn from their peers.
teachers often prefer small classes so they can provide each student with more personal attention.
ultimately, the benefits of collaborative learning opportunities in large classes outweigh the cost of less teacher attention.
some people ask for small classes so that they can provide people with more personal attention.

Explanation:

To build a strong introductory paragraph, we first establish a common preference for small classes (using "Teachers often prefer small classes so they can provide each student with more personal attention."), then introduce the counterpoint about large classes' peer - learning advantage ("However, large class sizes have the advantage of giving children more opportunities to learn from their peers."), and finally conclude with the overall stance on large classes' benefits ("Ultimately, the benefits of collaborative learning opportunities in large classes outweigh the cost of less teacher attention."). The sentence "Some people ask for small classes so that they can provide people with more personal attention." is redundant as it repeats the idea of the second sentence.

Answer:

Teachers often prefer small classes so they can provide each student with more personal attention. However, large class sizes have the advantage of giving children more opportunities to learn from their peers. Ultimately, the benefits of collaborative learning opportunities in large classes outweigh the cost of less teacher attention.
