Fourth Grade Students (Use estimation strategies (clustering around an average), and assess the reasonableness of answer

The video tutorial explains how to estimate the total number of 4th grade students in a school using the clustering around an average estimation strategy. It begins by presenting the problem of counting students across five classes, each with a different number of students. The tutorial then demonstrates how to estimate the total by rounding each class size to 20, resulting in an estimated total of 100 students. The exact total is calculated to be 102, showing the estimate is reasonable. The lesson concludes by reinforcing the estimation strategy taught.
