Social Studies: Area and Population Density

Will all the people be able to fit? Using historical population growth rates for continents, pupils determine estimates for the future population. The second day, pupils investigate whether a linear, quadratic, or exponential function...

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. 

Take young scholars on a trip through history with this unit on the mathematics and architecture of the Mayan civilization. Starting with a introduction to their base twenty number system and the symbols they used, this eight-lesson unit...

Evaluate young mathematicians' understanding of area and perimeter with this series of three assessment tasks. Challenging students to not only calculate the area and perimeter of irregular shapes, but to explain in writing their...

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...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The last day of...

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...

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...

Connecting math to furniture building comes in handy when the dimensions change and the cost of each piece needs to reflect the higher cost. Starting with a drawing of given quadrilaterals, learners calculate the original area and then...

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...
