Rene´ Decartes is the father behind his offspring, the coordinate system, useful in algebra and geometry. If coordinates are just not making useful sense to you in class, try out this instructive tutorial that shows you how to coordinate geometry's lines and points. This four-step lesson first introduces you to the apocryphal story of how Descartes came up with his idea. The second step shows how to place coordinates on a grid, and how to write an ordered pair. Once the foundation is laid, you practice with some problems, and finally you'll be able to see how you really score on a brief test. Included are the vocabulary words that you'll need to understand the concept and share in your next upcoming class.
This game helps build memory skills by exercising that part of your brain that requires concentration and attention to detail. Think of it as a muscle and by picking incorrect numbers you will strengthen the possibility of picking the correct one. You have choices of choosing numbers between 1 and 10, 1 and 100, and -1000 and 1000. As you guess, a chart shows whether your guess is too high or too low. By knowing that, you can focus in on the correct number. The catch is that you have only a certain number of guesses. If you choose to play the hard way, you’ll find out if your guesses are too high or too low, but you’ll have to remember what numbers you've picked.
What a great online subtraction game! Do you have a student who loves the thrill of a video game? Then he or she is going to love the excitement of this enrichment website. Count on Convict has an escaping convict, flashing search lights, and a police siren that sounds when you've answered the problem correctly. The game teaches children to find the difference when subtracting by using a number line. Figure out the distance the convict goes from his jail cell by answering the subtraction problem. In steps you move from the subtrahend, the number being subtracted, to the next 10 that you need to borrow from. Write your answer, check it, and catch the criminal. There is even a help button should you run into problems.
Can you imagine how hard it was to carry around enough coinage to purchase a big-ticket item prior to 1862? The only legal tender backed by the United States up until that time was in the form of coins. In February, 1862, as a way to finance the Civil War, the Legal Tender Act was passed, and the first paper money, the “Greenback,” was issued on March 10, 1862. This site from NOVA explores how the Treasury Department and Secret Service strive to keep our paper money hi-tech enough to thwart counterfeiters. After you’ve reviewed how a 100 dollar bill is made, try your hand at spotting a bogus bill.
