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. Grid method multiplication - Wikipedia

   en.wikipedia.org/wiki/Grid_method_multiplication

   Because it is often taught in mathematics education at the level of primary school or elementary school, this algorithm is sometimes called the grammar school method. [1] Compared to traditional long multiplication, the grid method differs in clearly breaking the multiplication and addition into two steps, and in being less dependent on place ...

4. Look-and-say sequence - Wikipedia

   en.wikipedia.org/wiki/Look-and-say_sequence

   This version of the pea pattern eventually forms a cycle with the two "atomic" terms 23322114 and 32232114. Other versions of the pea pattern are also possible; for example, instead of reading the digits as they first appear, one could read them in ascending order instead (sequence A005151 in the OEIS). In this case, the term following 21 would ...

5. Sierpiński triangle - Wikipedia

   en.wikipedia.org/wiki/Sierpiński_triangle

   Originally constructed as a curve, this is one of the basic examples of self-similar sets—that is, it is a mathematically generated pattern reproducible at any magnification or reduction. It is named after the Polish mathematician Wacław Sierpiński but appeared as a decorative pattern many centuries before the work of Sierpiński.

6. Mathematics - Wikipedia

   en.wikipedia.org/wiki/Mathematics

   Mathematics has a remarkable ability to cross cultural boundaries and time periods. As a human activity, the practice of mathematics has a social side, which includes education, careers, recognition, popularization, and so on. In education, mathematics is a core part of the curriculum and forms an important element of the STEM academic disciplines.

7. Kumon - Wikipedia

   en.wikipedia.org/wiki/Kumon

   All Kumon programs are pencil-and-worksheet-based, with a digital program that started in 2023. The worksheets increase in difficulty in small increments. [9] [10] Psychologist Kathy Hirsh-Pasek says that using such techniques for 2 to 12-year-olds "does not give your child a leg up on anything". [7] One study has observed a high percentage of ...

8. Number theory - Wikipedia

   en.wikipedia.org/wiki/Number_theory

   German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics." [ 1 ] Number theorists study prime numbers as well as the properties of mathematical objects constructed from integers (for example, rational numbers ), or defined as generalizations of the ...

9. Wallpaper group - Wikipedia

   en.wikipedia.org/wiki/Wallpaper_group

   Example of an Egyptian design with wallpaper group p4m. A wallpaper group (or plane symmetry group or plane crystallographic group) is a mathematical classification of a two-dimensional repetitive pattern, based on the symmetries in the pattern. Such patterns occur frequently in architecture and decorative art, especially in textiles, tiles ...
