The Whole numbers on the number line exercise appears under the 3rd grade (U.S.) Math Mission, Arithmetic essentials Math Mission and Mathematics I Math Mission. This exercise practices familiarity with the number line and with skip-counting.
Types of Problems
There is one type of problem in this exercise:
- Move the dot to the right spot: This problem provides a number line labeled with a scale and an orange dot. The user is asked to move the orange dot to a particular value on the number line.
Strategies
Since this problem is on the number line, experience with the number line is helpful. Being able to skip-count by single digit-numbers may be helpful but is not required.
- There are ten tick marks on the number line, this can be used to plot the points more quickly.
- The halfway mark is just beyond the end of the "question" which helps to estimate the middle point.
- The solution will always lie directly on one of the tick marks.
Real-life Applications
- Counting is essential for shopping, so people can count how many dollars they have and see if they have enough to purchase something.
- Fractions, decimals, and percents are used in many sports such as basketball to determine how many field goals the player has made over how many they attempted.
- Fractions are used in real life in lots of different ways, but are commonly used in cooking, construction and science.
