Printable interactive 100 number chart worksheets- color number patterns 1-100
The first Google hits for a printable 100 grid show fairly bad grids with unattractive fonts or rectangular, rather than square, grids.
This page, though it requires Flash, has a nice grid that will fill the whole page, with the add bonus of including an online game for children to colour in the grid, and then print it.

funny or not: conicity is funny, and so is glass purpose as far as cocktail mixing

dy/dan » Blog Archive » But How Do I Remediate THAT?
-
I tend to be highly skeptical of magic bullets, miracles, and so forth when I hear about them in the educational “literature” on-line. And I certainly don’t have any. But that doesn’t mean we shouldn’t continue to try to understand why some things do click unexpectedly or how to increase the percentage of kids we engage.
-
Having been in front of many at-risk/remedial classrooms, I can tell you that the kids HATE me for trying to “force” them to think and answer. They find it highly-disturbing when I won’t just give them the solutions immediately. And they quickly tell me that what I’m doing “isn’t mathematics” and “isn’t teaching.” They swear that what they want is “book work.”

Is this a joke? – Bad Science 2009
Home Office "statistics"

The Jill Dando Institute was asked by the HO if his notes could be published as an Appendix, and in the name of openness they said yes. He has been grievously upset ever since – long before Ben’s review. Hence the irony: this is not a story of a bad scientist but a good egg and just the sort of person who would read Bad Science with relish.

Teaching Math with the KDE Interactive Geometry Program | Linux Journal
Sounds similar to DrGeoII, but it can also display equations, so it may replace some uses of Mathematica, Sage or Gnuplot.

Add Sticky NoteThis also would be a great way to demonstrate the various trigonometric ratios, such as sin, cos and tan. In this case, you simply would construct a right angle, and let the student manipulate the lengths of the sides. Kig could be asked to display the angles and lengths of the sides, and the student then could calculate and verify the various ratios.
- I don't think DrGeoII has these measurements built-in, but it would be fun to add them in Etoys or Smalltalk. - on 2009-06-23

Add Sticky NoteKig has rudimentary support for vectors, including vector addition.
- Nice - but perhaps even better to combine it with symbolic algebra on vectors. - on 2009-06-23

This book is the most amazing book on algorithms I've read. The concepts are so well explained that moving to "An introduction to Algorithms by Cormen, Rivest" will be very easy.
I come from a non-computer science background.
The unreasonable effectiveness of logic Philip Wadler. Inaugural Lecture, University of Edinburgh, 16 November 2004. pdf
"A model of logic and a model of computing, each published at the dawn of the computer era, turned out, half a century later, to coincide exactly."
Haskell Curry and Java Generics
Wadler's Blog: Famelab: What does logic have to do with Java? video
Logic theorems and computer programmes can be exactly the same thing - this is now used to provide security through the Java type system.
Computer programs are discoveries.
Professor Phil Wadler explains, in a 3 minute video for non-scientists why he put formal logic in Haskell and then into Java.

You are correct that runtime checks are also needed, but static type checking is a crucial component of the Java security model. For instance, it is not possible to impose a dynamic arrays bound check (essential to avoiding buffer overflow exploits) unless you know which values are of type array.
Indeed, I don't know any secure system that does not use types; although some of them, such as Scheme, use a type system that is dynamically rather than statically enforced. Scheme is of particular interest because of the Scheme community's experiments with intermixing static and dynamic type checking.

These slides survey the software and recommend Axiom and Maxima
Quotes: "Commercial derivatives of MACSYMA in the 1980s were one of
Richard Stahlman’s motivations for creating project GNU" ... "2002 Axiom was released as free software by NAG
(Numerical Algorithms Group) which purchased it from IBM in the
1990s " "Axiom ... Huge library of functions "
(slides made with LaTeX beamer)
ICM/Kent:Computation Demos
These are live interactive demos that can prove to you that "open source" math tools like MAXIMA and Gnuplot really work - you don't need to install any software to type and test equations with these demos.

More open source packages for higher maths, and possible candidates for math pedagogy.

Add Sticky Notean interesting Rosetta Stone which offers translations of many basic operations for several computer algebra systems, including Maxima.

If you like calculus (even a little), and you like free stuff, you might find these screenshots stunning, as I do.
