The grid method (also known as the box method) of multiplication is an introductory approach to multi-digit multiplication calculations that involve numbers larger than ten. Because it is often taught in mathematics education at the level of primary school or elementary school , this algorithm is sometimes called the grammar school method.
The pictures on the right show how to calculate 345 × 12 using lattice multiplication. As a more complicated example, consider the picture below displaying the computation of 23,958,233 multiplied by 5,830 (multiplier); the result is 139,676,498,390. Notice 23,958,233 is along the top of the lattice and 5,830 is along the right side.
The managerial grid model or managerial grid theory (1964) is a model, developed by Robert R. Blake and Jane Mouton, of leadership styles. [1]This model originally identified five different leadership styles based on the concern for people and the concern for production.
In Forsyth, the leadership substitute theory is defined as "a conceptual analysis of the factors that combine to reduce or eliminate the need for a leader." [1] A leader may find that behaviors focusing on nurturing interpersonal relationships, or coordinating tasks and initiating structure, are not required in every situation. A study by Kerr ...
The leader is non-directive and never imposes a particular solution on the group. In this case, the final decision is one made by the group, not by the leader. Delegate The leader takes a backseat approach, passing the problem over to the group. The leader is supportive, but allows the group to come to a decision without their direct collaboration.
In mathematics education, there was a debate on the issue of whether the operation of multiplication should be taught as being a form of repeated addition.Participants in the debate brought up multiple perspectives, including axioms of arithmetic, pedagogy, learning and instructional design, history of mathematics, philosophy of mathematics, and computer-based mathematics.
A supervisor is responsible for the productivity and actions of a small group of employees. A supervisor has several manager-like roles, responsibilities and powers. Two key differences between a supervisor and a manager are: a supervisor typically does not have "hire and fire" authority and a supervisor does not have budget authority ...
Word problem from the Līlāvatī (12th century), with its English translation and solution. In science education, a word problem is a mathematical exercise (such as in a textbook, worksheet, or exam) where significant background information on the problem is presented in ordinary language rather than in mathematical notation.
