Course Description This course is the second in a two-part series designed for K–8 preservice teachers to address the conceptual framework for mathematics taught in elementary school. The focus of Part Two will be on measurement‚ geometry‚ probability‚ and data analysis. The relationship of the course concepts to the National Council of Teachers of Mathematics Standards for K–8 instruction is also addressed. Policies Faculty and students/learners will be held responsible for understanding

Mathematical model A mathematical model is a description of a system using mathematical language. The process of developing a mathematical model is termed mathematical modelling (also writtenmodeling). Mathematical models are used not only in the natural sciences (such as physics‚ biology‚ earth science‚ meteorology) and engineering disciplines (e.g. computer science‚artificial intelligence)‚ but also in the social sciences (such as economics‚ psychology‚ sociology and political science); physicists

CASE 1: Warren Buffett From Warren Buffett’s perspective‚ “intrinsic value is assessed as the present value of future expected performance” (Bruner‚ Eades‚ & Schill‚ 2010): in order to determine whether the investment is worth and is therefore fairly operating on the principle of achieving value for this investment. The displays volatility in earning corresponding to the fluctuation of prices will give investors the cheapest price when the investment shown by the discounted-flows-of-cash calculation
