Place Value & Decimals Fractions

​Multiplying Decimals by 10, 100, and 1,000

• ​Write thirty-six hundredths on your place value chart

• ​If we multiply this number, what is happening to the value?

• ​When the value gets larger, which direction are we shifting the digits?

• ​Multiply thirty-six hundredths by 10 --> what is the product?

• ​Multiply thirty-six hundredths by 100 --> what is the product?

• ​Multiply thirty-six hundredths by 1,000 --> what is the product?

​Dividing Decimals by 10, 100, and 1,000

• ​Write two thousand four hundred twenty-seven on your place value chart

• ​If we divide this number, what is happening to the value?

• ​When the value gets smaller, which direction are we shifting the digits?

• ​Divide two thousand four hundred twenty-seven by 10 --> what is the quotient?

• Now divide by 100 --> what is the quotient?

• ​Finally, divide by 1,000 --> what is the quotient?

​Expanded Form

• ​Expanded form = a number's value expanded and stretched out by individual digit values

• ​Write the expanded form for 4.56 on your white board

​Unit Form

​Unit form = the digit paired with its place value name

• Example: 6.7 = 67 tenths

• Write 0.56 in unit form on your whiteboard

​Standard Form

• ​Standard form = the number written using only digits

• ​Example: 6,702 is the standard form of six thousand seven hundred two

• ​Write the standard form for the following numbers

  • ​89 tenths

  • ​four and five hundredths

​Word Form

• ​Word form = a number's name written using words

• ​Example: 237.1 in word form is two hundred thirty-seven and one tenth

• ​Write 647.32 in word form on your whiteboard
