A few days in our Waldorf homeschool each week have a theme. We do these activities during our school time. These themes are built into our curriculum and integrated into our academic day. All are used to encourage and inspire learning in our homeschool via lots of opportunities for hands on learning. Some weeks I am able to do more with the themes than others. I admit, I am still finding my own rhythm in regard to school, school planning, menu planning, laundry etc since going back to work part time this past June.
Tuesday~ no theme
Friday~ no theme; occasionally this is Field Trip Friday
While the boys schedule and rhythm of days has some variance depending on the day of the week and their therapy schedules, and also on my work schedule (I work Wed and Thurs afternoons and Saturday mornings), the main anchor points of each day are the same for everyone, and the kids know what to expect each particular weekday.
