Some more lesson plans about africa including some interesting historical units. I also love the one titled "Africa, It's not a country" (there are even many adults that treat Africa like a country not a continent.)
Fascinating blog post about how misunderstanding the "pound sign" caused a project not to happen. The US school said to press the pound sign (#) but the UK school was looking for the british pound sign - they call the # the number sign. This is a great point about communication and overcoming. It makes me sad they couldn't figure it out and work it out, but great that these conversations keep happening.
