Estimation and Division Concepts

Mrs. Lamorn guides fifth graders through a math lesson on division using a real-world example of a Guinness World Record noodle. The lesson involves estimating the length of noodle each person would receive if a 10,119-foot noodle is divided among 400 people. Students explore different estimation methods, discuss their reasoning, and agree with Han's estimate of 25 and 1/4 feet per person. The lesson concludes with a reflection on the use of division and fractions in real-life contexts.
