REVIEW

Write down this problem on your COMMUNICATOR Be prepared to share your work with the class. Prepare for my Unit 5 Test By completing my practice test and making a 3x5 card of notes. Write down 5 Rational Numbers and 5 Irrational Numbers Defend your choices to your partner (justify your answers).

Have your homework out on your desk.

Try this CHALLENGE question: 0 It is the only Rational Number

Chapter 5’s Write them down on your 3x5 card. Notecards and Calculators can only be used on part of the test this time.

Benchmark Fractions MEMORIZE!!

Comparing Numbers When comparing numbers, they need to be in the same format (in this case: both decimal) Compare, using the symbol. >

Fractions Decimals 6.2

TERMINATING DECIMALS In your groups, discuss a way to sort these decimals into two groups … … … Types of Decimals REPEATING DECIMALS

0.3 Decimal Place Review What decimal place is this? tenth thousandth 0.34 hundredth thousandth

Do you see a pattern? Last time we converted repeating decimals to fractions, such as these examples… 0.555… Assign: x = 0.555… 0.444… Assign: x = 0.444… … Assign: x = … This Shortcut only works when the repeating numbers are right after the decimal … Assign: x = … So this type of equation does not follow the pattern. Do you see a pattern?

RATIONAL NUMBERS Decimals that terminate or repeat. Examples: and 0.555… IRRATIONAL NUMBERS Real numbers that are NOT RATIONAL The CRAZY Ones!
