Estimate the Sum

Mrs. Taylor teaches students how to round numbers to estimate sums, a useful skill for mental math and real-life applications like budgeting. The lesson includes step-by-step instructions and example problems involving cookies, pumpkin seeds, and festival attendees. Students learn to round numbers to the nearest tens, hundreds, and thousands, and then add them to find an estimated sum.

How do you round the number 186 to the nearest hundred?

What is the final estimated sum of visitors at the Fall Festival on Friday and Saturday?
