This is Book 2. It contains 100 days of more difficult patterns and logic puzzles (Answer Key Included). These aren't just fun puzzles. They're a sneaky way to develop geometry and algebra skills too. (Recommended for ages 10 and up) Skilled 10-year-olds may complete this book. Yet, many teenagers and adults will find this book challenging. (The challenge is part of the fun!) Addition, subtraction, multiplication, and division skills are needed. (A calculator may be used.) Visual-spatial skills are needed to solve many of the patterns and puzzles.

They're more than fun little brain teasers too. Pattern recognition frequently correlates with mathematical success. Developing Pattern Recognition Pattern recognition can be easier to learn than it is to teach. There are a few strategies that can be taught to help students recognize a pattern, but practice is usually the best teacher. Expose students to lots of patterns. Start with easy patterns and progress to more challenging ones. Don't forget to point out patterns in everyday life too. They're all around us.
