Learning Objectives
Students will be able to create numerical expressions containing multiple operations and a missing variable, and solve for the unknown number.
Introduction
(5 minutes)- Write '10 - __ = 6' and have students discuss how to solve for the unknown number.
- Engage students in a math talk about how they got their answer. Encourage students to explain their thinking, and welcome multiple strategies.
- Inform students that when they solve for a missing number in a math equation, they are beginning to learn about algebra, an area of math that will be an essential part of their lives as mathemeticians in fifth grade and middle school.
