What's the Problem?

Published on 09/03/2009

Activity Overview

Students will connect number sentences to problem situations and use addition, subtraction, multiplication, and division to solve the problems.

Before the Activity

On a sentence strip or on the overhead, display a number sentence such as "8 + 2 = ?" Have students brainstorm situations and related questions that this number sentence could be representing. For example, "If I bought eight postcards on my vacation and I had two postcards already at home, how many postcards do I have now?"

During the Activity

Demonstrate how to display this equation on the calculator, and how to tell the calculator what the value of ? is.
