Today we visit the only U.S. state with “West” in its name: West Virginia! There are no “East” states, but there are two pairs of “North” and “South” states (the Carolinas and the Dakotas). West Virginia is also home to the largest alluvial diamond ever found in the US. ‘Alluvial’ means that the diamond was loose on the surface when it was found. Nobody had to dig for it. In fact, the people that found it were just playing horseshoes! This diamond weighed more than 34 carats. It was named the Jones Diamond, after the family that found it. Some other gems in West Virginia are the town names. This state has many towns named after famous cities in other countries. So you can visit Athens, Cairo, Shanghai, Geneva, and more without even leaving the U.S.!
Wee ones: If there’s a North Carolina and a North Dakota, how many “North” states does that make?
Little kids: If you throw 5 horseshoes and every other one starting with the 2nd hits a diamond, how many diamonds do you hit? Bonus: There are 141 carats in 1 ounce. Which is bigger, a carat or an ounce?
Big kids: 3/4 of West Virginia is covered by forest! West Virginia is about 24,000 square miles in size. About how many square miles are clear of forest? Bonus: It’s a 130-mile long drive from Athens, West Virginia to Geneva, West Virginia, and a 1,505-mile long drive from Athens, Greece to Geneva, Switzerland. How much longer is the drive between European cities?
Wee ones: 2 states with North in their names!
Little kids: 2 diamonds: with your 2nd and 4th horseshoe. Bonus: Carats weigh less. Since there’s way more than 1 carat in 1 ounce, you know that carats are smaller.
Big kids: Just 6,000 square miles – a little more than the size of Connecticut. Bonus: 1,375 miles longer.
Laura Bilodeau Overdeck is founder and president of Bedtime Math Foundation. Her goal is to make math as playful for kids as it was for her when she was a child. Her mom had Laura baking before she could walk, and her dad had her using power tools at a very unsafe age, measuring lengths, widths and angles in the process. Armed with this early love of numbers, Laura went on to get a BA in astrophysics from Princeton University, and an MBA from the Wharton School of Business; she continues to star-gaze today. Laura’s other interests include her three lively children, chocolate, extreme vehicles, and Lego Mindstorms.
