Social Studies: Area and Population Density

Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...

Seventh grade statisticians randomly select five states and then determine the mean area. The class then works together to create a dot plot of their results. 

Utah is a large state, but what about it's population density? Pupils use a diagram of the state of Utah to estimate its area. Using the calculated area and the given population density, learners determine an estimate for the population...

Explore the fascinating study of population growth using real-time online growth calculators, animated maps, and primary sources. Have researchers get out their notebooks and, preferably, one computer for each one or two learners. They...

O, Canada! Young mathematicians explore population data for Canada and the US. They find a "Rough Rule of 10" (that the population of the US is roughly 10 times that of Canada) and then look at the population densities of US states.

Here is a very interesting visual for analyzing a country's shift from a pre-industrial society to one with an industrial or post-industrial economy. The video explains how a population pyramid is used to track a country's position in...

Students compare American South with India in terms of population density and food production. They practice math skills of estimation and calculation, visualize relative sizes of areas and populations, explore relationship between...

Young scholars examine population density in Jewish ghettos. In this Holocaust lesson, students calculate population density of cities around the world using the provided information. Young scholars then discuss the implications of high...

Students compare and contrast population densities throughout the world. Using maps, they estimate the relative size of the world's regions and populations. They develop analogies to discover the world they live in and hypothesize about...

Determine area using determinants. Young mathematicians use coordinates on a map to produce a 3-by-3 matrix and then apply the matrix to find the area of a triangular plot. They then convert this area to acres.
