2. Cubical complex - Wikipedia

   en.wikipedia.org/wiki/Cubical_complex

   Equivalently, an elementary cube is any translate of a unit cube [,] embedded in Euclidean space (for some , {} with ). [3] A set X ⊆ R d {\displaystyle X\subseteq \mathbf {R} ^{d}} is a cubical complex (or cubical set ) if it can be written as a union of elementary cubes (or possibly, is homeomorphic to such a set).

3. Everyday Mathematics - Wikipedia

   en.wikipedia.org/wiki/Everyday_Mathematics

   In October 1999, US Department of Education issued a report labeling Everyday Mathematics one of five "promising" new math programs. [7] The debate has continued at the state and local level as school districts across the country consider the adoption of Everyday Math. Two states where the controversy has attracted national attention are ...

4. Cube (algebra) - Wikipedia

   en.wikipedia.org/wiki/Cube_(algebra)

   In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 2 3 = 8 or (x + 1) 3. The cube is also the number multiplied by its square: n 3 = n × n 2 = n × n × n.

5. Hypercube graph - Wikipedia

   Construction of Q 3 by connecting pairs of corresponding vertices in two copies of Q 2. The hypercube graph Q n may be constructed from the family of subsets of a set with n elements, by making a vertex for each possible subset and joining two vertices by an edge whenever the corresponding subsets differ in a single element.

6. Triangular number - Wikipedia

   en.wikipedia.org/wiki/Triangular_number

   A square whose side length is a triangular number can be partitioned into squares and half-squares whose areas add to cubes. This shows that the square of the n th triangular number is equal to the sum of the first n cube numbers. Also, the square of the n th triangular number is the same as the sum of the cubes of the integers 1 to n.

7. KWL table - Wikipedia

   en.wikipedia.org/wiki/KWL_table

   The KWL chart was created by Donna Ogle in 1986. [2] A KWL chart can be used for all subjects in a whole group or small group atmosphere. The chart is a comprehension strategy used to activate background knowledge prior to reading and is completely student centered. The teacher divides a piece of chart paper into three columns.
