Practice Word Problems: Level 3 (Ages 11-13) (Competitive Mathematics for Gifted Students) (Volume 9) Silviu Borac 1.º edición

About ?Competitive Mathematics for Gifted Students? This series provides practice materials and short theory reminders for students who aim to excel at problem solving. Material is introduced in a structured manner: each new concept is followed by a problem set that explores the content in detail. Each book ends with a problem set that reviews both concepts presented in the current volume and related topics from previous volumes. The series forms a learning continuum that explores strategies specific to competitive mathematics in depth and breadth. Full solutions explain both reasoning and execution. Often, several solutions are contrasted. The problem selection emphasizes comprehension, critical thinking, observation, and avoiding repetitive and mechanical procedures. Ready to participate in a math competition such as MOEMS, AMC-8, Math Kangaroo in USA, or MATHCOUNTS? This series will open the doors to consistent performance.

About Level 3 This level of the series is designed for students who can solve linear equations, are fluent with fractions, and can factor into primes. The problem sets are designed to strengthen specific areas where we know students have difficulty on AMC-8 and AMC-10. The level 2 books are a strong preparation for AMC-8 and a partial preparation for AMC-10. Level 2 consists of: Word Problems (volume 9), Operations and Algebra (volume 10), Arithmetic and Number Theory (volume 11), and Combinatorics (volume 12). On the contest list for this level: MATHCOUNTS, Math Kangaroo levels 5-6 and 7-8, MOEMS-M, Purple Comet, AMC-8. The computational complexity makes these problem sets useful for preparing AIME in the long run.

About Volume 9 - Word Problems The problem sets offer a variety of applications of fractions, decimals and percentages. Some of the most dreaded categories of problems are thoroughly represented: mixtures, rates, and problems that engage comprehension. Mixture problems are among the problems that are underrepresented in other resources while being some of the more challenging word problems on AMC-10. The computational complexity familiarizes students with AIME level problems, albeit the easier problems on AIME. The full solutions provide insight in the optimal order of operations and a thorough description of the solving strategies.
