Flipped classroom teaching at Clintondale High School in Michigan, United States. A flipped classroom is an instructional strategy and a type of blended learning.It aims to increase student engagement and learning by having pupils complete readings at home, and work on live problem-solving during class time.

The Denver Developmental Screening Test (DDST) was introduced in 1967 to identify young children, up to age six, with developmental problems. A revised version, Denver II, was released in 1992 to provide needed improvements. These screening tests provide information about a range of ages during which normally developing children acquire certain ...
In mathematics, a symmetry operation is a geometric transformation of an object that leaves the object looking the same after it has been carried out. For example, a 1 ⁄ 3 turn rotation of a regular triangle about its center, a reflection of a square across its diagonal, a translation of the Euclidean plane, or a point reflection of a sphere through its center are all symmetry operations.
Inversion (discrete mathematics) Permutation with one of its inversions highlighted. An inversion may be denoted by the pair of places (2, 4) or the pair of elements (5, 2). The inversions of this permutation using element-based notation are: (3, 1), (3, 2), (5, 1), (5, 2), and (5,4). In computer science and discrete mathematics, an inversion ...
Inversive geometry. In geometry, inversive geometry is the study of inversion, a transformation of the Euclidean plane that maps circles or lines to other circles or lines and that preserves the angles between crossing curves. Many difficult problems in geometry become much more tractable when an inversion is applied.
[2] Contrary to the subject-auxiliary inversion, the verb in cases of subject–verb inversion in English is not required to be an auxiliary verb; it is, rather, a full verb or a form of the copula be. If the sentence has an auxiliary verb, the subject is placed after the auxiliary and the main verb. For example: a. A unicorn will come into the ...
Möbius inversion formula. In mathematics, the classic Möbius inversion formula is a relation between pairs of arithmetic functions, each defined from the other by sums over divisors. It was introduced into number theory in 1832 by August Ferdinand Möbius. [1]
An involution is a function f: X → X that, when applied twice, brings one back to the starting point. In mathematics, an involution, involutory function, or self-inverse function[ 1 ] is a function f that is its own inverse, f(f(x)) = x. for all x in the domain of f. [ 2 ] Equivalently, applying f twice produces the original value.
