An earlier Pentium II-class CPU chip from AMD. The first models were introduced in 1997 at 166 MHz, 200 MHz and 233 MHz clock speeds. Originally engineered by NexGen, AMD acquired the company in 1996. The K6 contained the MMX instructions used in Pentium MMX and Pentium II CPUs and plugged into Socket 7 on Pentium motherboards. The second-generation K6-2, introduced in 1998, improved performance and added AMD's 3DNow 3D instructions for faster rendering of games and animation. The K6-3 was introduced in 1999 with improved performance and greater onboard cache. The K6 series was superseded by the Athlon. See Athlon and K7.
Elementary school is grades K-6.
K-6 is defined as an abbreviation for the grades in school from kindergarten through sixth grade. K-6 stands for primary, or elementary school. It would refer to the first seven years of a child’s formal education.
An example of K-6 is the grade range in an elementary school where the child studies the core subjects of reading, language arts, math, science and social studies:
- Language arts include reading and writing, along with other related subjects, like spelling, punctuation, and grammar. It basically includes all things involved in literacy.
- Math starts with recognition of numbers and what they stand for and goes all the way to simple algebra and geometry.
- Science is the study of the natural world, so it starts with classifying leaves and observing rocks in kindergarten, to simple chemistry, and biology. The scientific method is reinforced with science fairs.
- Social studies start with family and community interactions, and develop into the study of history, economics, geography, politics, and anthropology.
