I've taught this unit for a few years, so it's a pretty solid unit at this point. This year I did some tweaks that felt like the icing on the cake!
Per the UBD (Understanding by Design) framework, I shared the long-term goal of the unit. I reminded on a daily basis the long-term objective and how the day's goal was connected.
We would be studying about different aspects of "lesser developed country" and the need to help a community and specific focus on children.
