Negative numbers on the number line

The topic  appears under the 7th Grade Math Mission. This exercise uses a number line to model the location of negative numbers

Types of Problems
There are two types of problems in this exercise:


 * 1) Tell the value of the position: This problem has a number line drawn and labeled with a blue dot. The student is asked to write the value of the position occupied by the blue dot.Nnotnl1.png
 * 2) Move the dot to the correct position: This problem has an orange dot at zero on a number line. The student is asked to move the orange dot to a specific position.Nnotnl2.png

Strategies
Experience with the number line model of the integers would provide adequate knowledge for doing this exercise.
 * 1) The scale on each number line is provided.
 * 2) Some number lines are presented horizontally and some are provided vertically.
 * 3) On the manipulative where the dot needs to be moved, there are five spots to left and five spots to the right. This knowledge can help improve efficiency by jumping to the far right or left and counting the opposite direction.
