Through the years I've been involved in co-ops for unit studies (KONOS--6 families, 12 plus children), science, history, writing, and art. Some have included just one other family.
I've used Mona Brookes' Drawing With Children at home (just my family), with good results, but have been part of a 6 family art co-op for going on 4 years now. We usually meet for 8-12 sessions per semester. In the past we've hired a "real" artist to teach drawing as well as work in varied media. We have so many students that we meet simultaneously (divided by age) at two nearby homes.
For our last several semesters we moms have led lessons from Discovering Great Artists. We present the artist and his (occasionally her) work, teaching some history and art appreciation. Then comes an art project related to the week's artist. The children have painted with melted crayons, watercolors, and tempera thickened with flour. They've made prints with wood and leaves, molded clay, and produced landscapes in several styles. We've worked our way through the Renaissance and into the Expressionist, Surrealist, and Abstract movements.
For my latest teaching turn I presented the British sculptor, Henry Moore (1898-1986). He was prolific, producing many small
as well as huge works.His early work, while not realistic is recognizable--women, mothers with children, families. Animal forms also interested him.
Moore sculpted lots of reclining figures like this one.This animal shape is more "inspired by" than a replication.For our art project, the children were to carve blocks of "stone". I mixed equal amounts of plaster and sawdust, then added enough water to get a mashed potato consistency.
Having a veterinarian for a husband means I have a big box of gloves in just my size. So handy!
Len has a dust collection system in the workshop that he has never emptied. This meant we had an ample supply of sawdust for my 23 blocks. The hardest item to gather was actually the 1/2 gallon containers; our family was happy to drink premium orange juice for a few months!
