Free or Reduced IPads For Homeschooling

Hello

I have two kids 5 and 11 that need IPADs for there homeschooling.

We had one that was shared but it was stolen a few months back.

My husband and I live from paycheck to paycheck and can not just go and get a new one

We are hopping to find a gently used or refurbished one or two for our kids to use for there schoolwork

Are there any programs to help us get a couple for them to use please and thank you
