This is what I started with. It's still quite a struggle for me to break it down to their level in one fell swoop. We talked about this briefly, and then moved on to the fun stuff!
Canopic jars, Egyptian gods, and organ playdough! Such thoughtful and engaging conversation about organ choices then versus what we know now, and concepts of afterlife.
Building a teeny playdough pyramid. They enjoyed trying bases of different sizes, and we had some great talks about 2d shapes working together to make 3d shapes.
A very unofficial translation of our names into hieroglyphics. Honestly, I was so impressed by their focus and attention to detail here.
We also had the privilege of visiting the mummy exhibit at the Indy Children's Museum and checking out plenty of realistic hieroglyphics.
