Transcript of Copy of Place Value for 4th graders

Why do we need to know place value?
Why is place value important? Place Value http://www.funbrain.com/tens/index.html uses digits only
numbers that "STAND'' alone Standard Form http://www.beaconlearningcenter.com/weblessons/whatsyourname/default.htm#page6 uses + symbols
shows the value of each digit using an addition symbol
"the elastic s+t+r+e+t+c+h+e+s out'' Expanded Form http://www.studyzone.org/testprep/math4/d/expandedform4l.cfm uses only words
spells out each number using letters
you should NOT see a numeral, but should READ the number words! Word Form http://www.ixl.com/math/grade-4 The ONEs' PERIOD has 3 places:
Ones' place - the first place and digit of any whole number.
the number is multiplied by 1 (ones' place!).
Tens' place - the second place and digit of any whole number.
this digit is multiplied by 10 (tens' place!).
Hundreds' place - this is the third place and digit in the ones' period.
the digit in this place is multiplied by 100 (hence, the hundreds' place). Ones' Period http://www.aaastudy.com/plc21bx2.htm The THOUSANDS' PERIOD also has 3 places:
Thousands' place - this is the fourth place/digit of a whole number.
this number is multiplied by 1,000 (thousands' place).
Ten thousands' place - this is the fifth digit/place of a whole number.
this number is multiplied by . . 10,000 (ten thousands' place!).
Hundred thousands' place - this is the sixth place of any whole number.
this number is x 100,000 (hundred thousands' place!). Thousands' Period http://www.aaastudy.com/plc21bx2.htm 1. Write 352,416 in EXPANDED FORM
2. Write 625,349 in WORD FORM
3. Write four hundred seventy-two thousand, five
in STANDARD FORM
4. 504,630 - write the # that is in the tens' place
5. 948,632 - write the # that is in the hundred
thousands' place EXIT TICKET! Recall the definitions of digits, period, place and value. Identify place value for each digit in numbers. I can . . . Explain standard form, expanded form, and word form. 0 1,000 2,000 3,000 4,000 5,000 6,000 7,000 8,000 9,000 10,000 100 200 300 400 500 600 700 800 900 10 20 30 40 50 60 70 80 90 1 2 3 4 5 6 7 8 9
