The Decimals on the number line 3 exercise used to appear under the 6th grade (U.S.) Math Mission, Arithmetic Math Mission and Pre-algebra Math Mission, but was apparently removed. This exercise practices visualization of decimals on a number line.
Types of Problems
There is one type of problem in this exercise:
- Move the dot to the correct spot: This problem provides a number line and a decimal number that may or may not be negative. The student is asked to move the dot to the correct spot on the number line.
- The number line always extends from negative two to positive two.
- The non-visible tick marks on the manipulate are labeled by tenths.
- It is sometimes easier to move from a larger number back a few spots rather than counting upwards every time.
- Decimals appear in every-day media to display information to consumers.
- Decimals are very common in shopping. Price tags, food labels, and receipts all contain decimals.
- At gas pumps, decimals are used to show how much gas is pumped and much it costs per gallon.
