Oki-Doku: Number Puzzles

The Common Core State Standards for Mathematics (CCSSM) (CCSSI 2010) emphasize the Standards for Mathematical Practice (SMP) that describe processes and proficiencies included in the NCTM Process Standards (NCTM 2000) and in the Strands for Mathematical Proficiency (NRC 2001). The development of these mathematical practices should happen in conjunction with the development of content and should provide a balance between procedures and understanding. During the elementary school years, most of the mathematical instruction focuses on developing number sense and operation sense. Being efficient and accurate when operating numbers is one of the most important skills that students must develop to support conceptual understanding. This has been recognized as the foundation for developing procedural fluency. Some curriculum materials have mathematical games to help students develop fluency. However, teachers who do not have access to such materials must search for other ways to develop fluency. In this article, the authors describe a specific type of number puzzle, an Oki-Doku, that is appropriate for elementary school students and requires students to make sense of a problem and persevere in solving it. A number of examples are provided for the reader to try on their own and instructions are given on how to construct the puzzles.
