For the states, we're using some very simple materials, including the giant state map already hanging in our playroom, two workbooks from the dollar section at Target, and some online resources. We're learning basic geography, state capitals, and a few fun facts, as well as peaking E's interest in traveling (again).
Having fun with the Spanish; mostly we're trying to learn some basic vocabulary (numbers, colors, animals, months) right now, as well as work on pronunciation. We have post-its up around the house with the Spanish words for common household items, and we're starting on conversational phrases.
As much as I love child-led learning, and will continue to follow E's lead in what we study, I think we both need more structure to our days and our curriculum as far as the how. I'm fairly certain this is driven by the fact that Hubby is gone for the next couple of months and when he's not around we all need more of a routine to stay sane. So, we're trying some things like daily assignment checklists and a set time each day to review our work. And I'm working on being more proactive with planning and keeping my own notes.
