Matlet. Una raccolta scelta e assistita di programmini, denominati applets, da usare online. Per permetterci di migliorare la nostra offerta, chiediamo cortesemente ai docenti di rispondere online al nostro brevissimo questionario di valutazione. Gli applets sono stati sviluppati dal “Freudenthal Institut Researchgroup in Mathematics education” di Utrecht, in Olanda nel corso di parecchi anni di ricerca e di sperimentazione. Ora alcuni di questi Applets sono messi a disposizione delle Scuole svizzere grazie alla disponibilità dell’Istituto olandese e al progetto comune sviluppato dal Centro didattico del cantone Ticino, dal Fritic del canton Friborgo e da ICT Basler Schulen del canton Basilea. Ogni programmino è accompagnato da una breve descrizione e da una scheda didattica dettagliata. Gli applets sono scritti nel linguaggio di programmazione Java. 60 APPLETS ORDINATI PER ARGOMENTO Numeri / Stima / Operazioni Equazioni Algebra / Calcoli Algebra geometrica Geometria.

Why do mathematicians and high school teachers disagree. Clever student: I know! Now we just plug in x=0, and we see that zero to the zero is one! Cleverer student: No, you’re wrong! You’re not allowed to divide by zero, which you did in the last step. This is how to do it: which is true since anything times 0 is 0.
Cleverest student : That doesn’t work either, because if then is so your third step also involves dividing by zero which isn’t allowed! And see what happens as x>0 gets small. So, since = 1, that means that High School Teacher: Showing that approaches 1 as the positive value x gets arbitrarily close to zero does not prove that . Is undefined. does not have a value. Calculus Teacher: For all , we have Hence, That is, as x gets arbitrarily close to (but remains positive), stays at On the other hand, for real numbers y such that , we have that That is, as y gets arbitrarily close to Therefore, we see that the function has a discontinuity at the point . But when we approach (0,0) along the line segment with y=0 and x>0 we get Therefore, the value of ! . As . . ? Wolfram MathWorld: The Web's Most Extensive Mathematics Resource.
Exploring Multivariable Calculus. And then relaunch Chrome. Instructors: If you are an instructor using this project in any way, please send me an email to let me know of your interest. I would love to see more people using the materials from this project, and it is important that I be able to report how the project is doing to the NSF. I also encourage anyone who is interested in this project to take the time to write something on the discussion board. You will need to become a member to do this, but I am the only one who will see this member information. It is a private website, and membership makes it easier to keep spam from being placed on the discussion board. The following PDF documents give more information about the goals and current state of the project. 9-27-2011 Graph implicit equations in spherical or cylindrical coordinates like rho^2 = -sec(2ϕ) or r^2*theta^2 = r +theta.Implicit surfaces/equations can now be graphed in spherical and cylindrical coordinates as well as in cartesian coordinates.

By Paul Callahan Rules of the Game of Life Life is played on a grid of square cells--like a chess board but extending infinitely in every direction. A cell can be live or dead. A live cell is shown by putting a marker on its square. A dead cell is shown by leaving the square empty. Each cell in the grid has a neighborhood consisting of the eight cells in every direction including diagonals. To apply one step of the rules, we count the number of live neighbors for each cell. A dead cell with exactly three live neighbors becomes a live cell (birth). Note: The number of live neighbors is always based on the cells before the rule was applied. In Life, as in nature, we observe many fascinating phenomena. The rules described above are all that's needed to discover anything there is to know about Life, and we'll see that this includes a great deal. Life Patterns A good way to get started in Life is to try out different patterns and see what happens.

Math Monday: Hula Hoop Geometry, Part 1. By Glen Whitney for the Museum of Mathematics Math Mondays have so far featured a wide array of different items from which one can make a tremendous variety of geometric constructions, but there has not yet been one on hula hoops. This week and next we’ll remedy that oversight. Also, the postings so far have almost entirely shown the constructions as fait accompli, so this series will also try to give a bit of insight into the process of devising a new creation.
First, why hula hoops? They’re a pretty cheap source of large, pre-made circles, generally decently symmetric and strong. Assignment: can you do the same thing with six hula hoops? For a recent event, MoMath wanted a large-scale public construction activity, so based on our success with hula hoops to date, designer Tim Nissen envisioned a gigantic pyramid of hoops — here’s the initial conception: We even managed to combine four of the order-1 units into an order-2 tetrahedron pretty nicely: To be continued… Gareth Branwyn Related.
Math Learning Disabilities. While children with disorders in mathematics are specifically included under the definition of Learning Disabilities, seldom do math learning difficulties cause children to be referred for evaluation. In many school systems, special education services are provided almost exclusively on the basis of children’s reading disabilities. Even after being identified as learning disabled (LD), few children are provided substantive assessmentAssessment is a broad term used to describe the gathering of information about student performance in a particular area. See also formative assessment and summative assessment. and remediation of their arithmetic difficulties. This relative neglect might lead parents and teachers to believe that arithmetic learning problems are not very common, or perhaps not very serious.
Different types of math learning problems As with students’ reading disabilities, when math difficulties are present, they range from mild to severe. Mastering basic number facts In summary.
