Reflection: Checks for Understanding Addition in the Real World - Section 3: Practice the Concept


This lesson was less challenging for my students than I had expected.  They were comfortable with the idea of joining word problems.  However, I am not sure whether or not they would be able to identify each word problem as a joining word problem in a different context.  

After teaching this lesson, I added a slide to the PowerPoint presentation.  This slide allows you to assess whether the students can identify the joining stories.  It is a nice way to think about what information your students already know about upcoming topics you are going to teach.

Addition in the Real World

Unit 1: Addition and Subtraction Basic Training
Lesson 3 of 7

Objective: The students will be able to create part/part/whole models to demonstrate addition in word problems and write the appropriate number sentence.

Big Idea: The big idea of this lesson is that we can think of addition in the real world as the joining of two parts to make a whole. The use of addition number sentences can show how we join the parts to make the whole.
