This ''plan'' said that congress should be made up of one house and that each state should have equal representation in congress

Explanation:

During the United States Constitutional Convention in 1787, there was disagreement over how Congress should be constituted.  The large population states wanted representation in Congress to be based on a state's population size. This was the Virginia Plan.  The smaller states feared this would lead to unchecked dominance by the big states; they wanted all states to receive the same amount of representation.  Their plan was known as the New Jersey Plan.

Ultimately, a compromise plan was proposed.  The Connecticut Compomise, also known as the Great Compromise, created a bicameral (two-chamber) legislature, with different rules for representation in each chamber. Representation in the House of Representatives would be based on population.  In the Senate, all states would have the same amount of representation, by two Senators.  This was the plan enacted for the formation of the US Congress as we know it.
