For parents
Goal: Your child learns about the planned Indus Valley cities and the invention of paper in China.
Ask: what did the drains do? Why is that helpful in a city?
Hold a sheet of paper and a heavy book. Ask which would be easier to carry on a long trip.
Away from the screen: Find Pakistan, India and China on a globe. Trace the Indus River and the Yellow River with your finger.
