How does Origami relate to math?
105012
You can build all (or most of) the platonic and archimedaic solids using Origami.\n\nYou can also buid conic sections (hyperboles, parabola, ellypse and circle) by repeatedly folding a piece of paper along the tangents, point by point, using fundamental properties of each one. (= you get them as the envelope of their tangents).

how does this fit into mathematics?

I know of two:\n\nTranslation and rotation: \n\n1) translation :\n\n Take a rectangle and cut a diagonal and extended the lines  from all three side of the triangle at right angle to it  from the side that is made from cutting the rectangle until those lines equal the lenght of the side of the triangle drawn from  and it  form three boxes  around all three sides of the triangle. Now let take the big side an calulate the square  of it ,then calulate the squares of the other two sides and add themup,  it should equal the square of the big side and that proves the pythagorean theorem. \n\nRotation: \n\nSee the show : Project Mathematics by Cal tech : Entitled "The Pythagorean Theorem" it explain better  than I can, It worth watching. Very good show on Math & Geometry

I don't believe it can.  This is an example of a unicursal problem and you can find some more details at the puzzle link in the reference below, you'll need to scroll down to puzzle number 51.\n\nFrom my days of O Level Maths I remember that we touched on these and I seem to recall that there was an equation to do with the number of vertices and nodes that a shape had which would determine if it was unicursal or not.\n\nBasically only unicursal shapes (those with a specific ratio of nodes and vertices) can be drawn without removing a pencil from the page and without tracing over an existing line.\n\nI'll leave further research to you.\n\nHave fun

Try this, maybe?\n\nhttp://mathforum.org/library/drmath/drmath.elem.html

ok i'm not doing your homeowkr for you, but i'll help.  you're unclear about some things:  number cube?  you mean a six-sided die?  in that case, one roll can give you: 1,2,3,4,5, or 6.  which ones are perfect squares?  let's see: 1^2=1, 2^2=4, 3^3=9>6 therefore just 1 and 4 are perfect squares.  so what's the probability or rolling a 1 or a 4 out of the possibilities 1,2,3,4,5, or 6?\n\nprobability=what you want/what you CAN get.

Try analogy especially for math. Or do it with illustrations.

What does this have to do with math?

What do you mean by "calculate" in this context?  If I have 5th graders working on least common multiples or 2nd graders working on subtraction, I just "make up" problems for them.  If I need a lot of different worksheets on the same topic, I build an Excel spreadsheet that makes the kind of problems I need using the random number function, constrained to get numbers of the size and type my kids are working on.  I used Excel for worksheets in Algebra topics in high school, too.

Algebra is needed for SO many things! Recipes, budgeting you name it. It teaches problem solving. Geometry is good to shape your mind to think logically. I actually took geometry twice out of my own free will because I loved proving the angles were equal or whatever. My mind was never so sharp. Trig, well I actually haven't found a use for that yet....

I don't know, but try these websites to see if they work. Good luck! You can go to the local library and borrow some origami books.\nwww.origami-instructions.com\nwww.paperfolding.com \nwww.origami.as \norigami.ousaan.com \nen.wikipedia.org/wiki/Origami \nwww.tammyyee.com/origami.html \nwww.toilegami.com/glasses.php \nwww.opane.com/origami.html

Not sure, but all of the paper sizes tie into each other. It has to do with filing.  Fold a 11x17 in half, you get a 8.5x11...fold a 22x34 in half you've got 11x17, fold again 8.5x17.......you get the picture. Not sure where it all started though!

Algebra and all the Maths that one learns at school and college are tools which are ultimately used by Scientists, engineers, doctors, and almost all the people who have something to do with science. Even social scientists like historians and sociologists use it. \n\nIt may seem abstract but Maths is the underlying machinery of the Universe.

Rhombus and square (c)\n\n\nThis can be proved using geometry, analytic geometry, etc.  But it is the case.  Surprisingly, a general reactangle and parallelograms don't have perpendicular diagonals.\n\nGeneral kites do, and a rhombus is a kite with all equal sides.  A square can be thought of as a type and rhombus and rectangle, or just a rhombus when each angle is 90 degrees.  Then it makes sense that it would have perpendicular diagonals.

you can create numbers and shapes out of cardboard\ncreate cone/hat out of nice colored paper.\nand of course put a string trough with needle

yes we did it in science class.  I forget how exactly but you fold the paper and then start cutting tiny rows but everyother row you change directions and then open it up when you are done and you get a loop of paper like a hoop and then you can step through it.
