At my school all teachers follow a looping schedule. This allows kids to keep the same teacher for two years in a row. The looping is as follows: K-1, 2-3, 4-5. I am in the 5th grade year currently (which is always the more challenging of the two...but I'll save that for another time).
So why do we do this? 85% of out student population qualifies for free and reduced breakfast and lunch. Many of out families have struggles bigger than we can imagine. Looping, keeping the same teacher for two years, creates more stability for our families and allows us to really build a strong relationship with these students over two years. As an added bonus, we don't have to spend the second year getting to know 25 new kids. We can dive right in!
