Solving Multi-Step Word Problems with Whole Numbers

Subject:
Math, Operations and Algebraic Thinking

Type:
1 Hour Lesson

CCSS: 4.OA.3, CCSS.MATH.PRACTICE.MP1, CCSS.MATH.PRACTICE.MP6

Skills: solving multi-step word problems, reasoning skills using mental computation and estimation strategies, making sense of problems and using perseverance to solve them, attention to precision

Description: In this 1-hour lesson plan, 4th grade students will 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. Students will also 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, and explain why a rounded solution is appropriate.
