Have your students explore this interactive from the Census Bureau to learn more about the characteristics of single-family homes built and sold in 2018. Putting the cursor over the yellow circle and blue squares in the interactive reveal information about the specific feature in the house. Lots of opportunities for math teachers teaching percents with this interactive as students can calculate how prevalent each home feature is. 


  • What was the median square footage for a new home built in 2018? sold in 2018? 
  • What was the average sales price for new home sold in 2018? 
  • Calculate the cost per square foot for the new home sold in 2018 based on your answers to the first two questions.
  • What percent of new homes sold had more than 4 bedrooms? 
  • Which home features were most prevalent in new homes SOLD? Which were least prevalent? This question requires analyzing each of the home features and calculating the percent of each new home SOLD that had that specific feature. 
  • BONUS: What percent of homes that were built in 2018 were also sold in that same year?
