This PowerPoint presentation introduces the concept of Comparative Relational Thinking using addition expressions modeled on number lines. Through the use of animated slides, students are acquainted with Comparative Relational Thinking and walked through the process of using it to determine if two addition expressions are equal.
After an introductory example, the presentation includes a second worked example, an example with two expressions that are not equal, and two student practice problems to check for understanding.
To assist you as you present the content, there is also a Teacher Notes document. These notes include screenshots of each iteration of the slides along with a teacher script and the desired student responses to all questions. These notes outline every single click throughout the presentation, with notes corresponding to each click organized into separate rows.
This presentation can be used to teach Fourth Grade Mathematics Florida Standard MAFS.4.OA.1.a: Determine whether an equation is true or false by using comparative relational thinking. For example, without adding 60 and 24, determine whether the equation 60 + 24 = 57 + 27 is true or false.
