We (my 4, almost 5, year old and I…and sometimes my 2 year old) are part of a small homeschool co-op consisting of 7 kiddos (and some younger siblings) who are all currently 4 and 5 years old. We meet once a week and the moms take turns putting a themed lesson together. We’ve been doing this for three years now and have, obviously, tailored what we choose to teach based on the kids’ ages.
