15. Fractions  Decimals Repeating Decimals
Some decimals form a pattern that goes on and on forever and ever. If I start seeing the same number over & over again, then I know it will be a repeating decimal.
To show that it repeats, I put a line over the number(s) that repeat.
Like this:

16. Fractions  Decimals 6 6 6
Repeating Decimals . 3
2.0 2 18 2
0.666 .6 18 2 18 2
