This does not introduce the concept of pattern in any meaningful way, and it uses an overly broad and inconsistent definition of pattern. Is pattern about repetition? Is it just the configuration or design/form of something?
The book is also mostly not asking kids/readers to engage with patterns. Identifying colors on a striped sock is not engaging with the pattern. Tracing a spiral staircase is not engaging with a pattern. There are a couple of "what patterns do you see?" pages near the end.
