"Math educators always seek great problems and tasks for the classroom, and this collection contains many that could be used in various grades. By using this book, the reader will understand ways that great problems can be used to encourage student participation and to promote powerful mathematical ideas. In addition, suggestions for how problems can be presented in the classroom will provide professional development to teachers in the form of effective routines for promoting problem solving. This book would be both a fun read for NTCM's membership"--

Both a challenge to mathematically inclined readers and a useful supplementary text for high school and college courses, One Hundred Problems in Elementary Mathematics presents an instructive, stimulating collection of problems. Many problems address such matters as numbers, equations, inequalities, points, polygons, circles, ellipses, space, polyhedra, and spheres. An equal number deal with more amusing or more practical subjects, such as a picnic ham, blood groups, rooks on a chessboard, and the doings of the ingenious Dr. Abracadabrus. Are the problems in this book really elementary? Perhaps not in the lay reader’s sense, for anyone who desires to solve these problems must know a fair amount of mathematics, up to calculus. Nevertheless, Professor Steinhaus has given complete, detailed solutions to every one of his 100 problems, and anyone who works through the solutions will painlessly learn an astonishing amount of mathematics. A final chapter provides a true test for the most proficient readers: 13 additional unsolved problems, including some for which the author himself does not know the solutions.

Problems that beset Archimedes, Newton, Euler, Cauchy, Gauss, Monge, Steiner, and other great mathematical minds. Features squaring the circle, pi, and similar problems. No advanced math is required. Includes 100 problems with proofs.

Why Do Students Often Have Trouble Counting Beyond 100? And what we can do to help them with this hurdle. Certainly, when you think about mathematics, you think about numbers. When you think about learning mathematics, you might have great thoughts of the quest to tackle problems that unlock applicable solutions. Ask any lower elementary student to count aloud for you and chances are they will stop counting at 100. It doesn't matter if you ask them to count by 1s or to skip-count by 5s or 10s, 100 forms a natural stopping point. The problem arises when you ask young students to go further. "What comes next?" I ask my young math students. Many students are unsure about counting beyond 100, especially if I ask them to write the numbers on paper.100-a number not too small, not too large, but just right to challenge students without intimidating them. It's used in myriad ways within the problems: as an exponent, product, area, or perimeter; a constant in an equation; the number of items in a series or sequence; or as a physical value, such as a stack of 100 coins, a deck with 100 cards, or a jug that holds 100 ounces. There is something magical about the number 100, and these problems aim to capture some of that magic. But no matter how 100 is used, each problem is meant to spark curiosity and motivate students (and their teachers) to want to solve it.

A collection of 25 books are featured with instructions on how to use each title to launch a classroom math lesson.
