Each month for 8 months, Mary read 4 books. How many more books does she need to read before she has 45 books?

In 8 months, Mary read 4 books each month, which totals to 32 books (4 books x 8 months = 32 books). To find out how many more books she needs to read to reach a total of 45 books, you subtract the number of books she has from 45: 45 books - 32 books = 13 books. So, Mary needs to read 13 more books to reach her goal! This scenario is a great way to practice basic math skills such as multiplication and subtraction while understanding goal-setting in reading. Setting measurable targets, like reading a certain number of books each month, can make it easier to track progress and stay motivated!
