7.NS.2d

7.NS.2d. Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.

I like to start with a warm up where students are given fractions which already have a denominator of 10,100,1000, or is easy to rewrite as that type of fraction. The last fraction on the warm up is one that is a repeating decimal- which is a great way to explain the difference between a terminating and repeating decimal.

- I had students show their work for converting the fractions to decimals in the box below each fraction. In their notebook, students titled one page "terminating" and the other "repeating" and as they converted each fraction they cut them out and glued/taped them on the appropriate page. There are 12 fractions- 6 repeating and 6 terminating. One is an improper fraction.

- Twelve problems...start with one letter, the answer is at the top of a different problem...circles around to the beginning, so students can start anywhere. Includes a mixture of terminating and repeating decimals.
