Does this source leave out concepts of citizenship when they could be added for deeper context?
The Grandfather Tang story is a great way to open the conversation about tangrams because of the way Grandfather Tang talks about and imagines animals. This story is ripe for conversations about cultural differences and conversations about what is means to be a citizen. This resource is ripe for that because Grandfather Tang is of Asian descent and the value that his perspectives bring to the life of his grandchild is something to be celebrated across differences. It is an opportunity to discuss with students the value of a diverse citizenry. With the right preparation and educator might be able to give some historical context for the diversity of America, particularly as it relates to the US's relationships with Asian immigrants.
My first graders will love this lesson!
