Practice the ancient art of Mathjitsu, Kar-add-e, Tai-sub-tract. And please, make sure to do it with friends. In this ninja-styled game, your mission is to navigate your ninja through the treacherous game board by using the four basic math operations. A Ninja Recruit will have an easier time with the riddles, but may not move as fast across the board. A Ninja Mathster - I mean Master - will have the addition of multiplication and division dice to roll with, giving a mobility edge, but the challenges are harder. Once you make it to one of the four "Number Ninja challenge cards", you must answer a math riddle in order to unlock a piece of the Golden Dragon. In one card, Yamamoto's aunt may have kites to sell, or Fujimoto is taking pictures of animals in his back yard, requiring you to use a mix of math operations to solve the problem. Who cares if Oshima is counting tiger stripes? You do. It could mean the difference between victory and defeat! ~ Stephen

When children are young, we teach them to recognize sequences, shapes, and patterns as prerequisites to math – important skills to build upon. This book from The Critical Thinking Company incorporates some fun puzzles to work with children at the fifth to seventh grade level to really get them thinking about math functions. Five different types of puzzles make the math exploration challenging – Pattern Predictor, Equality Explorer, Sequence Sleuth, Number Ninja, and Function Finder. There are eight of each type for a total of 40 puzzles that become progressively more difficult. Pattern Predictor asks the student to look at a pattern of shapes and predict where the pattern will be in future stages. Equality Explorer is like Balance Benders (also by Critical Thinking Press) where the student sees a series of balances with shapes on one side and a number on the other – the student has to figure out the value of each shape in order to equal the number on the other side (balancing equations). Sequence Sleuth shows a sequence of patterns, objects, letters, etc. and asks a series of questions in which the student is to determine future stages in the sequence based upon what they can already see. Number Ninja lays out a series of operations and tells you a starting or ending number. Based on the operations you have to determine the missing start or finish number. The fifth type of puzzle is the Function Finder in which the student is to determine what functions are being employed given the example presented – look for a pattern and understand it. An example of this last puzzle would be 6♦7=43, 8♦3=25, 9♦10=91, 2♦5=11. Based on the mystery function offered here, what would the answers be to 5♦9 and 16♦3? The mystery functions would be multiply and add one, so the answers would be 46 and 49, consecutively.
Hints for solving the puzzles and solutions are offered at the back of the book. These are very helpful when you get stuck.
I know this book says that it is for 5th – 7th grade, but I feel like the number-brain exercises in these puzzles would be good for even high school and adults. I have completely enjoyed working the puzzles in this book. Like other Critical Thinking products, this book is reproducible for classroom and family use. ~ Donna
