Lucky Beans is a book about the depression era, when there was not a lot of money or jobs.  Marshall was tired of eating beans at his house but he knew he should be grateful for what they had.  The local store was having a contest for a new sewing machine that his mom could only wish for.  If you could guess the correct number of beans the the jar you would win the sewing machine.   Marshall’s family figured out a way to estimate the number of beans in the jar.

I liked the math that was in the book.  This would be a great book for 3rd graders to use in class and estimate the number of beans in the jar.
