## Reflection: Unit Exams Assessment of Unit Concepts: Addition and Subtraction Story Problems - Section 3: Assessment: Addition and Subtraction Story Problems

When looking at the students work, you want to make sure that students can make sense of the action in the story by choosing the correct operation and create an accurate equation. You'll also want to note:

• what strategies do they use?
• do they get the right answer?
• do they see the relationship between the numbers in the last two questions of the assessment?

The examples included show how this student used a number line to solve each task.  She also demonstrates that she understands the relationship between making 10 and making 20.

It is important that students represent counting back from right to left to signify that they are moving down the number line when they are solving removal situations.
