ExploreLearning is a Charlottesville, Virginia -based company which operates a large library of interactive online simulations for mathematics and science education in grades 3–12 called 'Gizmos'. ExploreLearning also makes Reflex, an online, game-based system for math fact memorization. [1] ExploreLearning is a business unit of Cambium ...
As with any simple polygon, the sum of the internal angles of a concave polygon is π × ( n − 2) radians, equivalently 180× ( n − 2) degrees (°), where n is the number of sides. It is always possible to partition a concave polygon into a set of convex polygons. A polynomial-time algorithm for finding a decomposition into as few convex ...
ATNR is an acronym that stands for asymmetrical tonic neck reflex. It’s a primitive reflex that babies exhibit and is part of the development of muscle tone, consistent one-sided movements with ...
The plantar reflex is a reflex elicited when the sole of the foot is stimulated with a blunt instrument. The reflex can take one of two forms. In healthy adults, the plantar reflex causes a downward response of the hallux ( flexion ). An upward response ( extension) of the hallux is known as the Babinski response or Babinski sign, named after ...
These movements mimic the early reflex movements and include simple games, exercises, and age-appropriate activities. The aim is to create new learned neural pathways to help with ATNR integration.
The Babinski reflex — also called the plantar reflex — is a response to stimulation of the bottom of the foot. It can help doctors evaluate a neurological problem in people over age 2. If your ...
Encouraging movement. Your baby’s startle reflexes will begin to disappear as they grow. By the time your baby is 3 to 6 months old, they probably won’t demonstrate the Moro reflex any longer ...
Multiple representations (mathematics education) In mathematics education, a representation is a way of encoding an idea or a relationship, and can be both internal (e.g., mental construct) and external (e.g., graph). Thus multiple representations are ways to symbolize, to describe and to refer to the same mathematical entity.
