As student enter the room, they will have a seat, take out their Problem of the Day (POD) sheet and begin to work on the question on the SMARTboard. The POD also allows students to use MP 3 continually based on the discussions we have about the problem each day.
What is the difference between |24| and |-5|? Describe the placement on a number line.
I chose this question because a common misconception my students have is about the concept of absolute value. They usually assume that positive integers have greater absolute value. We need to make it evident, using a number line, what the absolute value actually refers to. During our discussion, I will ask them to compare |-24| to |5| as well. I need them to recognize that it is the distance on the number line, not whether the number is positive or negative that determines the greater absolute value.
The target for the day is also on the SMARTboard each day when students enter the room. The target for today’s lesson is for students to understand absolute value and the placement of those values on a number line and what that placement means.
I will use responses to this prompt as a MyFavoriteNo as the Problem of the day for the next lesson.
Where does the answer to (-14) + (14) fall on the number line? How do you know?
