1 Place Value, Word, Expanded and Standard Forms

2 Decimals show amounts between two consecutive counting numbers (3,4…) 0.45 is between 0 and is between 3 and 4 25,196.8 is between 25,196 and 25,197

3 Decimal word names always end in -th or -ths one tenth0.1 four hundredths0.04 seven and three tenths7.3

4 The decimal is represented by the word and when writing and saying decimals in words. 2.1 = two and one tenth 4.5 = four and five tenths = seventeen and sixty-one hundredths

5 To write a number containing a whole number and decimal follow these steps: A. Write the whole number in words B. Write and C. Write the numbers shown in the decimal D. Write the last place a digit occupies in the decimal (the farthest right) A. thirty-two B. and C. forty-six D. hundredths thirty-two and forty-six hundredths

6 Write the place individually =

7 Write the place individually = 5

8 Write the place individually =

9 Write the place individually =

10 Write the place individually =

11 Multiply the digit by the value of the corresponding place =

12 Multiply the digit by the value of the corresponding place = (5 x 1)

13 Multiply the digit by the value of the corresponding place = (5 x 1) + (3 x 0.1)

14 Multiply the digit by the value of the corresponding place = (5 x 1) + (3 x 0.1) + (6 x 0.001)

15 Multiply the digit by the value of the corresponding place = (5 x 1) + (3 x 0.1) +(6 x 0.001)

16 To put a number in standard (numeral) form from expanded form, just add all places together

17 To put a number in standard (numeral) form from expanded form, just add all places together

18 To put a number in standard (numeral) form from expanded form, just add all places together (be sure to line up your decimals)

19 To put a number in standard (numeral) form from expanded form, just add all places together

20 Standard form of one hundred thirty and three tenths Expanded form of 0.56 Word form of 0.234
