Sample Sequential Reasoning Puzzles
Color Network Puzzle
Each circle is to be colored Red (R), Yellow (Y), or Blue (B). However no two vertices of a triangle are permitted to be the same color. What must be the color of the circle marked with a question mark?
A knowledge of chess is not necessary in order to solve these puzzles. A rook moves horizontally or vertically, but not diagonally. Fill in the missing numbers 1- 49 for puzzle 14. For puzzle 20, fill in the missing numbers to generate a continuous path in each square.

Mathematical Connections: Euler Paths
If all the edges of a network, called a graph in Graph Theory, can be covered without retracing any edge, then the graph has an Euler path. If all edges of a graph can be covered without repetition and you can return to the starting point, then the graph has an Euler circuit.
A Magic Square is a square array of distinct integers such that the numbers in any row, column, or main diagonals, have the same sum (called the magic sum). The magic square below is a normal 4x4 magic square.
A magic square puzzle is an incomplete magic square. Complete the 5x5 magic square. You will need to calculate the magic sum first.

Angle Chase Puzzles
Students rely on their recall of geometry properties (and can review them in Appendix 4), not their protractor, when solving Angle Chase puzzles. The puzzle below uses properties of parallels, vertical angles, isosceles triangle properties, and polygon sum properties. Find the measures of all the angles in the Angle Chase puzzle below.
This article describes four different sequential reasoning puzzles (and each puzzle has many variations). These puzzles, played as part of your school mathematics curriculum, make great classroom openers, end of period thought provokers, or for students to work on at home during school breaks. The puzzles in Smart Moves are wonderful for cooperative problem solving activities in the classroom. You can project a worksheet onto a screen as the class solves the puzzle together. I encourage parents to participate in these games and puzzles with the entire family. Sequential reasoning puzzles can provide a setting for children and grandparents to work on problem solving and mental exercises together. Try them. I think you’ll see the “reason” for including them in your lesson plans.
