  6. Standard • Number Sense 1.3: Convert fractions to decimals. • Number Sense 1.5:Know that every rational number is either a terminating or repeating decimal and be able to convert terminating decimals into reduced fractions.

  7. 08/30/11 08/30/11 Observe, Question, Comment Rational Numbers: Fractions and Decimals Rational Numbers: Fractions and Decimals Reflection Warm-Up: Standard: Objective: 7L 7R

  8. Objective • To find equivalent fractions • To write fractions in simplest form • To write rational numbers as decimals • To write terminating and repeating decimals as fractions

  10. VocabularyRational Numbers • Is any number you can write as a fraction.

  11. VocabularyTerminating Decimal • Is a decimal that ends, which means that a terminating decimal doesn’t keep going.

  12. VocabularyRepeating Decimal • A decimal in which a pattern of one or more digits is repeated indefinitely, for example, 0.353535 ... Also called recurring decimal
