Why was is important that madison kept notes on the constitutional convention?

It made making a new constitution easier.

Explanation: When James Madison and the other 56 delegates to the Constitutional Convention met in Philadelphia in May 1787, they intended to amend the Articles of Confederation. They ended up creating a new constitution, and Madison, representing Virginia, became the chief recorder of information (he took a lot of notes).

i'm free to do it

explanation:

native american contribution: the patriots from britain learn how to hunt, fish, and introduce diversity within cultures.

african americans: indirectly introduced the idea of diversity to americans. africans coming to america because of slavery taught white americans that people come from different backgrounds and colors. it also built america's economic stability for a great period of time. 

women: make america what it is today. there are some societies that are in the world currently that do not give women the same right we give women here in the united states. because women have rights here in the united states, other countries' citizens strive to come to america, especially women, since they have equal rights in the united states. this is important because america is seen and desired by many in the world. 

children: children are our future. we learn from our elders and carry out things the same or differently learning from america's history. we continue tradition and change tradition if it is needed.
