There are some FREE homeschooling resources on two small tables in the instrument room (labeled music office) behind the Choir Room. Come and take whatever would be helpful. Come anytime the church is open, these doors are not locked.
Also, check out the Curriculum Closet in the main building, upstairs on the Missions Cafe side. Get a key from Stephanie at the front desk. Those books can be borrowed for as long as you need them.
