Books like Math contests for grades 4, 5, and 6 by Steven R. Conrad

Problem-Solving Strategies is a unique collection of competition problems from over twenty major national and international mathematical competitions for high school students. The discussion of problem-solving strategies is extensive. It is written for trainers and participants of contests of all levels up to the highest level: IMO, Tournament of the Towns, and the noncalculus parts of the Putnam competition. It will appeal to high school teachers conducting a mathematics club who need a range of simple to complex problems and to those instructors wishing to pose a "problem of the week," "problem of the month," and "research problem of the year" to their students, thus bringing a creative atmosphere into their classrooms with continuous discussions of mathematical problems. This volume is a must-have for instructors wishing to enrich their teaching with some interesting nonroutine problems and for individuals who are just interested in solving difficult and challenging problems.

A compilation of over one thousand problems from the Berkeley exams for mathematics students preparing for PhD programs, this book aids in problem-solving skills development across various mathematical areas, including real analysis, multivariable calculus, differential equations, metric spaces, complex analysis, algebra, and linear algebra.
