# Check Multi-step Word Problems (Grade 4)

Videos, examples, solutions, and lessons to help Grade 4 students learn to solve multi-step word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

Common Core: 4.OA.3

Multi-Step Word Problems

Estimate to judge the reasonableness of an answer - 4.OA.3
In this lesson, you will learn to judge the reasonableness of an answer by estimating.
Examples:

1. It took me 38 minutes to take the train. Then another 11 minutes to walk to the football stadium. My family members guessed how long the trip will take me. Which guesses are reasonable?
2. A beekeeper has 3,216 bees and wants to distribute them evenly among 8 new hives. How many bees can go in each hive? Classify each value below as a reasonable or unreasonable answer to the problem.
