US Customary Length
Dec 7, 2021
Today I'm going to talk about U.S. customary measurement and their units for length. In the United States, we use U.S. customary. We are the only developed country not to use the metric system. What do we use here in the United States? Well, we use inches. Feet. Yards, and miles. To talk about length. When we talk about measuring length of an object, we have to include the unit of measure. If I'm going to talk about a box, let's say, about the size of a shoe box, I'm going to measure that in what? Inches. Feet, miles, it matters. One foot equals 12 inches. Three feet equals one, yard. And 1000 760 yards equals one mile. Why do you think I haven't mentioned centimeters, kilometers, meters? Because all of those are the metric system. And we'll talk about them another day. Now, try to solve on your own, how many inches are in a yard. How many feet are in a mile? Jot your answers down. Did you know that you have an inch in your pocket? Right there. This is approximately one inch. Check it out and see. One foot is 12 inches. One yard is three feet. And this track, if you run around at four times, equals a mile. Now go ahead and create a table with a piece of notebook paper that looks like this. You may fold your notebook paper into fourths. And label the first box inch, the second box foot, the next one, yard, and the last one mile. Your job right now is to list or draw at least two things that you would measure with each of these different measurement lengths. Feel free to draw pictures or just to make a list, but if you can think of more than two, that would be fantastic. I can't wait to see you tomorrow.
