Water: Math Lesson

Wrap-up

Once you get the hang of reading pie charts, graphs, and maps, you can interpret, compare, and represent all sorts of data. Now each time you watch the raindrops fall, turn on the tap, or drink a glass of water, think about how you can measure and represent the flow of water in our lives. Cheers!

In this lesson you:

• Compared how quantities are represented on different charts and graphs
• Interpreted data on a map
• Calculated percentages
• Learned what volume is and how to measure it

On your own:

• Find out how much rainfall your city or state had last year. How does that compare with averages of other cities?
• Use an on-line search tool to find out the water content of different foods that you eat on a given day. Which food has the highest percentage of water? Which has the lowest? Create two pie charts that compare these amounts.
• Look at a recipe for your favorite meal. Identify which ingredients are measured by weight and which are measured by volume.
• Keep track of how much water you drink each day. Use a conversion chart to help you describe that amount in multiple ways—for example, how many cups, quarts, gallons, liters, etc. did you drink?
• Conduct online research to compare the volume of water used by individuals in different countries.
• Measure the volume of different objects in your home.
