2. Pattern Blocks - Wikipedia

   en.wikipedia.org/wiki/Pattern_blocks

   Pattern blocks were developed, along with a Teacher's Guide to their use, [1] at the Education Development Center in Newton, Massachusetts as part of the Elementary Science Study (ESS) project. [5] The first Trial Edition of the Teacher's Guide states: "Work on Pattern Blocks was begun by Edward Prenowitz in 1963.

3. Mathematics of paper folding - Wikipedia

   en.wikipedia.org/wiki/Mathematics_of_paper_folding

   The major question about such crease patterns is whether a given crease pattern can be folded to a flat model, and if so, how to fold them; this is an NP-complete problem. [32] Related problems when the creases are orthogonal are called map folding problems. There are three mathematical rules for producing flat-foldable origami crease patterns ...

4. Manipulative (mathematics education) - Wikipedia

   It is important for young children to create patterns using concrete materials like the pattern blocks. Pattern blocks can also serve to provide students with an understanding of fractions; because pattern blocks are sized to fit to each other (for instance, six triangles make up a hexagon), they provide a concrete experiences with halves ...

   Examining divisibility by 5 as well, remainders upon division by 15 repeat with pattern 1, 11, 14, 10, 14, 11, 1, 14, 5, 4, 11, 11, 4, 5, 14 for the first polynomial, and with pattern 5, 0, 3, 14, 3, 0, 5, 3, 9, 8, 0, 0, 8, 9, 3 for the second, implying that only three out of 15 values in the second sequence are potentially prime (being ...

6. Barnsley fern - Wikipedia

   en.wikipedia.org/wiki/Barnsley_fern

   The fern is one of the basic examples of self-similar sets, i.e. it is a mathematically generated pattern that can be reproducible at any magnification or reduction. Like the Sierpinski triangle , the Barnsley fern shows how graphically beautiful structures can be built from repetitive uses of mathematical formulas with computers.

7. List of open-source software for mathematics - Wikipedia

   en.wikipedia.org/wiki/List_of_open-source...

   This free software had an earlier incarnation, Macsyma. Developed by Massachusetts Institute of Technology in the 1960s, it was maintained by William Schelter from 1982 to 2001. In 1998, Schelter obtained permission to release Maxima as open-source software under the GNU General Public license and the source code was released later that year.
