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).

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!! 0.50.25 0.75 0.125 0.375 0.625 0.875

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. 0.888… 0.264 -6.15 0.758574 0.5 4.123123… -1.222… Types of Decimals REPEATING DECIMALS

0.3 Decimal Place Review What decimal place is this? tenth 5.347 thousandth 0.34 hundredth 0.347 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… 0.151515… Assign: x = 0.151515… This Shortcut only works when the repeating numbers are right after the decimal. 0.1333… Assign: x = 0.1333… So this type of equation does not follow the pattern. Do you see a pattern?

RATIONAL NUMBERS Decimals that terminate or repeat. Examples: 0.356 and 0.555… IRRATIONAL NUMBERS Real numbers that are NOT RATIONAL The CRAZY Ones!

Perfect Squares MEMORIZE THEM 1 4 9 16 25 36 49 64 81 100 121 144

Square Roots UNDO Squares 2 INVERSE OPERATIONS

Square Roots of Perfect Squares 2 3 4 5 6 7 8 10 9

Square Roots UNDO Squares INVERSE OPERATIONS We can use this inverse operation to solve equations with exponents.

Find the Side, given the Area 6 ft.

Between which two Integers would you find… Square Roots jkkkk

Perfect Cubes MEMORIZE THEM 1 64 8 125 27

Cube Roots UNDO Cubes 3 3 INVERSE OPERATIONS

Cube Roots of Perfect Cubes 2 3 4 5

Cube Roots UNDO Squares INVERSE OPERATIONS We can use this inverse operation to solve equations with exponents.

Find the edge, given the Volume 2 m.

Cube Roots Foldable: Highlight the Perfect Cube Between which two Integers would you find…

CALCULATOR REVIEW SQUARE ROOTS CUBE ROOTS / ANY ROOTS # = 3

1, 2, 3, 4…0 … -4, -3, -2 -1 Decimals that repeat and terminate Decimals that do not terminate or repeat 0.444… 0.125 0.6543986204… X

No Calculator or Notecard on First 2 Pages Do the CIRCLED PROBLEMS on the PRACTICE TEST. When you finish, you can work on the rest of the problems. PRACTICE TEST

CIRCLED ANSWERS 3b. 7 in. 4b. 2 in. 6b. 321/100 6e. 215/99 8a & b

What’s your Score? Each answer part is worth 1 point 73 possible Now, finish the rest of the Practice Test!!!
