Final answer:
Providing translators at the PTO meeting while covering meaningful topics for ELL families
Step-by-step explanation:
The option that would encourage the greatest involvement by families of English Language Learners (ELLs) in the Parent-Teacher Organization (PTO) would be providing translators at the PTO meeting while covering meaningful topics for ELL families.
By offering translators, families of ELLs would be able to understand and participate in the discussions and activities of the PTO. This would create a more inclusive environment and encourage greater involvement from these families. It is important to cover topics that are specifically relevant to ELL families to ensure that their needs and interests are addressed, making them feel more connected and motivated to engage with the PTO.
