Two lessons, 1 dealing with Social Security taxes and the other with the Dow Jones industrial average, are presented along with 10 questions and answers designed to demonstrate to students that mathematics is useful, current, and newsworthy. (AIM)

Discusses how mathematics can be used as an analytical tool to give backbone to all the sciences. (CCM)

3 experiments were conducted to assess young (5-7 years) children's ability to judge the relative amount that a character would receive if sharing a material with 1 friend (halves) or 2 friends (thirds). Materials included items that appeared in 3 forms: continuous, discrete, and composite. In the first 2 experiments, performance was best with…

This article describes how to determine your return on investment when deposits of varying amounts are made over irregular time intervals.

This article presents an alternative to the traditional method of multiplying polynomials, FOIL. The method can be used with any size of polynomial.

The connection between linear and 0-1 integer linear formulations has attracted the attention of many researchers. The main reason triggering this interest has been an availability of efficient computer programs for solving pure linear problems including the transportation problem. Also the optimality of linear problems is easily verifiable…

This article describes an alternate way to utilize a circular model to represent thirds by incorporating areas of circular segments, trigonometric functions, and geometric transformations. This method is appropriate for students studying geometry and trigonometry at the high shool level. This task provides valuable learning experiences that…

In this article we present a segment of Sulinet Digital Knowledgebase curriculum system in which you can find the sections of subject-matter which aid educating the database management. You can follow the order of the course from the beginning when some topics appearance and raise in elementary school, through the topics accomplish in secondary…

This study assessed the effects of small-group tutoring with and without validated classroom instruction on at-risk students' math problem solving. Stratifying within schools, 119 3rd-grade classes were randomly assigned to conventional or validated problem-solving instruction (Hot Math, schema-broadening instruction). Students identified as at…
