Everything in Mrs. Jewls's class has gone topsy-turvy...again. The report cards are scrambled, the pop quiz won't pop, and watermelons are falling out the windows. On top of all that, the boys are upset because Allison has announced that only two of them will be invited to her birthday party, since if more than two boys come, they'll all start acting silly. You never know how things will add up at Wayside School.

Do high-speed, complicated arithmetic in your head using the Trachtenberg Speed System.Ever find yourself struggling to check a bill or a payslip? With The Trachtenberg Speed System you can.

He devised a set of rules that allows every child to make multiplication, division, addition, subtraction and square-root calculations with unerring accuracy and at remarkable speed. It is the perfect way to gain confidence with numbers.

This book is the result of a unique experience: a research mathematician teaching in an elementary school. It tells about a fascinating discovery made by the author -- that elementary mathematics has a lot of depth and beauty, and that the secret to its teaching is in understanding its deep points.The first part of the book discusses the nature of mathematics and its beauty. The second part tells about the teaching principles the author distilled from his experience. The third part is an excursion through the arithmetic studied in elementary school, accompanied by personal stories, historical anecdotes and teaching suggestions. The appendix relates the fascinating story of modern day politics of mathematical education.The book was a bestseller in Israel, and has been translated into many languages. The extraordinary combination of mathematical and didactic insights makes it an essential guide for parents and teachers alike.

The acclaimed author of A Tour of the Calculus and The Infinite Ascent offers an enlightening and enthralling tour of the basics of mathematics, and reveals a world of fascination in fundamental mathematical ideas. One, Two, Three is David Berlinski’s captivating exploration of the foundation of mathematics, its fundamental ideas, and why they matter. By unraveling the complex answers to these most elementary questions—What is a number? How do addition, subtraction, and other functions actually work? What are geometry and logic?—Berlinski reveals the intricacy behind their seemingly simple exteriors. Peppered with enlightening historical anecdotes and asides on some of history’s most fascinating mathematicians, One, Two, Three, revels in the beauty of numbers as Berlinski shows us how and why these often slippery concepts are as essential to the field of mathematics as to who we are.

Computers And Thought by Edward A. Feigenbaum is a comprehensive book that explores the relationship between computers and human thought. The book delves into the history of computer science and artificial intelligence, and how these fields have impacted our understanding of human cognition. It also examines the ways in which computers have been used to model human thought processes, and how these models have been applied to various fields such as psychology, linguistics, and philosophy.Feigenbaum discusses the different approaches to artificial intelligence, including rule-based systems, expert systems, and neural networks. He also explores the limitations of these approaches and the challenges of creating truly intelligent machines. The book includes case studies of successful applications of artificial intelligence, such as the development of chess-playing programs and natural language processing systems.The author also addresses ethical and philosophical questions related to artificial intelligence, such as the possibility of machines surpassing human intelligence and the implications of this for society. He argues that while computers can simulate human thought processes, they cannot replicate the full range of human experience and consciousness.Overall, Computers And Thought is a thought-provoking and informative book that provides a comprehensive overview of the relationship between computers and human thought. It is a valuable resource for anyone interested in the history and future of artificial intelligence and its impact on society.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.

Many elementary teachers who have taught time-telling skills would propose that the mathematical skills associated with time-telling are among the most difficult for young students to learn. This booklet was developed to relate some of the concepts of time to physical models, providing methods for isolating specific time-telling concepts within a concrete framework. The time-telling of each hand of the clock is presented separately, with the major focus on using the hour hand. The booklet contains stories, activities, games, bulletin board ideas, and worksheets designed to accommodate a range of teaching and learning styles. Many of the activities in the booklet's seven sections are also designed to help integrate mathematics with other areas of the elementary school curriculum, such as social studies, language arts, and science. Reproducible worksheets and blackline masters are included in the back of the book. (TW)
