Glossary

班
はん

Typically used to describe lunch and field trip groups, "han" is the Japanese word for "group". A han tends to consist of 4-6 kids. In a single classroom, there can be up to 10 hans with 4 kids each. In field trips, there can be far more than 10 if multiple classes are participating.

Keeping this in mind, it is recommended to always make at least 10 sets of an activity so that there are enough materials for every group.  

What your coworkers are saying when calling out the groups: 
Group #1: ippan
Group #2: nihan
Group #3: sanpan
Group #4: yonhan
Group #5: gohan
Group #6: roppan
Group #7: nanahan
Group #8: happan
Group #9: kyuuhan
