CONFIDENTIAL 1 GOOD AFTERNOON Today we will be learning about "Place Value". Let's do a few practice problems before we get started. 1.)5 x 5 x 3 = 2.) = 3.)6 x 5 ÷ 3 = 4.)554 ÷ 2 =

CONFIDENTIAL 2 Let's review what we covered the last time we met!

CONFIDENTIAL 3 VERY GOOD!! ARE YOU READY TO CONTINUE WITH TODAY'S LESSON?

CONFIDENTIAL 4 The location of the digit in a number identifies the PLACE VALUE of that digit. The digits in a whole number are in groups of 3. Billions Millions Thousands Ones Hundreds Tens Ones Hundreds Tens Ones

CONFIDENTIAL 5 Billions Millions Thousands Ones Hundreds Tens Ones Hundreds Tens Ones 310, 458, 298, 126 Let's look at the following number written in Standard Form Each digit has its place value below. (Standard Form is the usual way to write a number.) In what place is the digit 4? What is the value of the digit 4?

CONFIDENTIAL 6 Billions Millions Thousands Ones Hundreds Tens Ones Hundreds Tens Ones 310, 458, 298, In word form, we can write the number as Three hundred ten billion, four hundred fifty-eight million, two hundred ninety-eight thousand, one hundred twenty-six. standard form In what place is the digit 9? What is the value of the digit 9?

CONFIDENTIAL 7 Billions Millions Thousands Ones Hundreds Tens Ones Hundreds Tens Ones 36, 245, 046, 378 Can you express this number in word form? (Notice that there is a 0 in the Hundred Thousands place.) standard form In what place is the digit 7? What is the value of the digit 7?

CONFIDENTIAL 8 Decimals are similar to Whole Numbers. The digit and the location of each digit determine the value of the decimal. The decimal point separates the whole number from the decimal. tenths hundredths thousandths ten-thousandths This part to the right of the decimal is LESS THAN 1

CONFIDENTIAL 9 The decimal point separates the whole number from the decimal. tenths hundredths thousandths ten-thousandths Let's write 42, in word form. Forty-two thousand, eight hundred seventy-six AND two hundred fifty-four thousandths In what place is the digit 5? What is the value of the digit 5?

CONFIDENTIAL 10 tenths hundredths thousandths ten-thousandths When we say or write 42, , we use the word "and " to separate the whole number part from the part less than 1. Forty-two thousand, eight hundred seventy-six AND two hundred fifty-four thousandths " AND "

CONFIDENTIAL 11 Let's try to say the following decimals: You can write them here if this will help you. tenths hundredths thousandths ten-thousandths

CONFIDENTIAL 12 The decimal point separates the whole number from the decimal. tenths hundredths thousandths ten-thousandths You try one..... How would you "say" the following number? 678, What is the value of the digit 3? In what place is the digit 3?

CONFIDENTIAL 13 tenths hundredths thousandths ten-thousandths How would you "write" and "say" the following number? 40, Print your number here Write your number in words here

CONFIDENTIAL 14 LET US TAKE A SHORT BREAK!

CONFIDENTIAL 15 WE WILL NOW DO A JIG-SAW PUZZLE!!! piece-jigsaw/ clownfish.html

CONFIDENTIAL 16 A decimal is made using each digit 4, 8, and 2 one time. What is the greatest possible decimal greater than 4 and less than 8 that I can make?

CONFIDENTIAL 17 A decimal is made using each digit 4, 8, and 2 one time. What is the smallest possible decimal greater than 0 and less than 1 that I can make?

CONFIDENTIAL Plot the following decimals on the number line. A.6.2 B. 7.5 C.5.8

CONFIDENTIAL 19 Review Problems: 1.) Can you write "Seventy-two thousand, three hundred fourteen and twenty-seven hundredths " in Standard Form? 2.) Can you write the number 234,120,400.6 in Word Form? 3.) In the number 2,135, a.) In what place is the digit 9? b.) What is the value of the digit 3? c.) In what place is the digit 7? d.) What is the value of the digit 4? e.) In what place is the digit 2?

CONFIDENTIAL 20 4.) Circle the part of this decimal that is less than 1? 567, ) How would you say the following decimals: a.).8 b.) 4.03 c.).108 d.)

CONFIDENTIAL 21 Good Job! We learned a lot today! We learned that we can write numbers in Standard Form ( ex. 45, ) and in Word Form (ex. Forty-five thousand, seven hundred eighty-nine and twelve hundredths) We learned that the location of a digit in a number identifies the Place Value of that digit. In other words, each digit in a number has a PLACE and a VALUE.

CONFIDENTIAL 22 We learned that the part of the number to the right of the decimal point is LESS THAN 1. We learned that the decimal point separates the whole number from the decimal. CONGRATULATIONS ON A GREAT LESSON!
