Many teachers using "Challenge Math for the Elementary and Middle School Student" have requested a similar book for younger students. This book teaches thinking and math problem solving skills using the fun characters that appear in the other Zaccaro math books. Problems at four levels of difficulty are included that test a student's application of each concept as it is learned. The book is designed for advanced math students in grades 1-4, however it also works well for older students with grade level math skills. Teachers may reproduce pages for use with their students.

Primary Grade Challenge Math offers material that goes beyond calculation skills for those children who enter the primary grades already knowing basic concepts. This book allows parents and teachers to instill a deeper level of mathematical understanding and thinking skills in young children while nurturing a love of mathematics. (Grades 1st - 4th) 

Each chapter's questions are broken down into four levels: 
Level 1 (easy) 
Level 2 (somewhat challenging) 
Level 3 (challenging) 
Einstein (very challenging) 

Includes chapters on: Sequences, Problem-solving, Money, Percents, Algebraic Thinking, Negative Numbers, Logic, Ratios, Probability, Measurements, Fractions, Division.
