Estimating Reasonableness of Fraction Word Problems using Benchmark Fractions

This video tutorial teaches how to estimate the reasonableness of answers to fraction word problems using benchmark fractions. It introduces benchmark fractions like 1/4, 1/2, and 3/4, and explains the concept of reasonableness with logical examples. The tutorial includes a practical problem where Emmitt needs to jog a certain distance, and demonstrates how to calculate and estimate the total distance using fractions. The video concludes by comparing the calculated and estimated answers to ensure they are reasonable, reinforcing the learning objectives.

What was the estimated distance Emmitt thought he would jog, and how did he arrive at that estimate?

Discuss the significance of comparing calculated answers to estimates in problem-solving.
