One of the basic underpinnings of U.S. democracy is that we use voting to determine who represents us at the city, state, and federal levels of government. The U.S. Congress—that collection of 100 senators and 435 voting representatives that gather in Washington, D.C. to create and vote on things like laws, taxes, wars, and budgets—is the primary institution that gives voters representation in the federal government. 
For these challenges, you will be charged with adhering to one of the three traditional redistricting principles as you draw districts in simplified “states.” Many state laws offer guidelines about how to “draw within the lines” to maintain pre-existing communities of interest, jive with natural topography like rivers and mountains, and stay within county or state lines. In that spirit, you may only draw districts by tracing along the gray lines in this resources challenges. Good luck!
