The topic Integers on the number line used to be a topic under the 6th grade (U.S.) Math Mission. This exercise helps to visualize the location of integers on the number line.
Types of Problems
There are two types of problems in this exercise:
- Move the dot: This problem provides a number line and an orange dot located at zero. The student is asked to move the orange dot to a particular value.
- Locate the dot: This problem provides a number line and a blue dot on the number line. The student is asked to use the line and the scale to infer the location of the dot.
Strategies
This exercise is medium to get accuracy badges because it is necessary to be careful with scale between different problems. Once mastered, thespeed badges are easy because the manipulative is simple to use.
- It is necessary to expect both positive and negative numbers, but not fractions or decimals.
- The answers will land on actual tick marks, not between them.
- The number line has five dashes to the left and the right of zero, so this can be used to help jump to correct answers and spots on the number line itself. For example, if the scale is 3, the furthest tick mark to the right is 15.
Real-life Applications
- Knowing how to count is essential for learning algebra and the higher maths, and counting is used for almost everything humans do.
