Solving Word Problems Using Multiplicative Comparisons4th Grade • Half Day Lesson Plan
Subject: Math, Operations and Algebraic Thinking
Skills: Multiplication and Division, Solving Word Problems, Additive Comparisons, Multiplicative Comparisons, Using Variables, Tape Diagrams
File Type: PDF Document
Materials Needed: blank paper, pencil, document camera or whiteboard, manipulatives – Unifix cubes, marbles, buttons, etc., and measurement tape or rulers
Printable Resources: Optional: printable “Exit Slips” (as an optional assessment component) (1 copy per student)
Lesson Plan Description
This half day of lesson plans is broken down into 3 separate segments (30-60 minutes each) addressing Operations and Algebraic Thinking: multiplicative comparisons (4.OA.A2). These lessons include: key terms, helpful student notes for reference, guided and independent practice of concepts, and an activity to reinforce the concept of solving word problems using multiplicative comparisons, tape diagrams, and manipulatives.
- Segment 1: students will be able to distinguish between additive comparison and multiplicative comparison. Solve word problems by multiplying or dividing numbers. They will also be able to solve word problems using drawings and equations with a letter for the unknown variable.
- Segment 2: students will continue to solve word problems by multiplying or dividing numbers. They will also be able to solve word problems using drawings and equations with a letter for the unknown variable.
- Segment 3: students will show their understanding of the multiplicative comparison by creating word problems and using manipulatives to illustrate their solutions.
These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
