Overview
Mystery Grid puzzles consist of grid-based number problems that function similarly to Sudoku puzzles. These puzzles are solved through arranging colored, numbered tiles in a grid so each tile appears once in every row and every column. Additionally, these puzzles include math clues of inequality symbols and multiple operations. Mystery Grid puzzles support computational thinking, algebraic fluency, and logical reasoning.

Mathematical Concepts
Mystery Grid puzzles provide practice for the following mathematical concepts:
  • Operations
  • Inequalities
  • Integers
  • Fractions
  • Algebraic equations

There are three levels of Mystery Grid puzzles. It is beneficial to start with the beginning level puzzles to gain a basic understanding for the game. After a strong foundation has been built, feel free to choose an appropriate range of puzzles for your students. The levels include:
  • Explorer: small 3x3 to 5x5 grids with a focus of only whole-numbers
  • Puzzler: medium 4x4 to 6x6 grids with a focus on integers and more challenging clues
  • Master: large 7x7 grids with a focus on fractions and algebraic equations
Connection to the Math Practice Standards
Mystery Grid encourages the development of the following mathematical habits of mind:
  • Computational thinking
  • Algebraic fluency
  • Tracking and managing multiple constraints
  • Reasoning strategically rather than guessing
