I purchased this book for my first grade classroom. I read the book to the students during a math lesson. The first day, I split the students into groups and had them count how many pockets they had all together. They recorded it on a chart and answered questions like: Who had the most? Who had the least? Choose two numbers and compare using <,>,=. The second day we referenced the book and compared pockets of the boys vs the girls. They again answered questions about the numbers. They loved it! Recommend!!
