Query: Excellent introduction to logical thinking for young children

This book contains simple logic puzzles for young children. The puzzles are all classic "grid-style" logic puzzles. These are mostly one-square style puzzles which means that only two traits are being matched. This means this book is perfect for introducing logic puzzles to a younger child. My son has fallen in love with these puzzles! Highly recommend.
