1 Ordering Decimals #1 Write the whole numbers in order from least to greatest. You need to line them up and use your magical decimal reader! , #2 Write the numbers shown below in order from least to greatest. You need to line them up and use your magical decimal reader! #3 Write the numbers shown below in order from greatest to least. You need to line them up and use your magical decimal reader! #4a What is the biggest number you can make with these numbers? You have to include a whole number and you cannot add zeros #4b What is the smallest number you can make with the same numbers? You have to include a whole number and you cannot add zeros. #5 Order the following fractions and decimals from greatest to least. Hint: Write them all in decimal form first! 76/ /1,

2 Rounding/Estimating Decimals #1 Round to the nearest whole number: #2 Round to the nearest hundredth: #3 Use estimation to plot these numbers on the number line. Label each point. ANSWER THIS QUESTION ONLY WITH AN EXPO MARKER. ERASE AFTER YOU HAVE CHECKED #4 Sarah spent $25.66 on jeans and $1.55 on a Diet Coke. Using estimation, about how much did Sarah spend? #5 Round to the nearest thousandth: #6 Laura wants to buy a rotisserie chicken for $5.99, corn for $1.05, and bread for $2.60. Will $9 be enough? Use estimation to decide. Place Value

3 #1 Draw out a place values chart by memory from thousands to thousandths (there should be 7 total including thousands and thousandths). #2 Copy and circle the numbers in the hundredths spot #3 Copy and circle the numbers in the thousandths spot , , #4 A beehive is home to 1,000 bees. If 235 bees are out gathering pollen, what decimal number do those bees represent? #5 Write the following fractions in decimal form: 54/100 23/1000 4/10 443/1000 3/100 #6 This number has a 4 in the tenths spot, a 3 in the hundredths, and a 9 in the thousandths. What number is it? #7 This number has a 4 in the tens, a 8 in the tenths, and a 1 in the thousandths. What number is it? Comparing Decimals #1 I know that 17 > 9, but how is 0.17 < 0.9?

4 #2 I know that 456 > 8, but is greater than 0.8? #3 Write the inequality in between the following numbers. For each you must write down on a separate sheet of paper in order to line them up vertically and then compare using your magical decimal reader #4 Circle the value that does not fit in the line: / /1,000 Expanded/Word Form #1 What is expanded form? Write the definition and an example.

5 #2 What is word form? Write the definition and an example. #3 Write the word form for the following numbers (remember, the only time you write AND is when there is a decimal point!): #4 Write the expanded form for the following numbers (remember, break down EACH part of it) #5 What different kind of forms would you find on a check? (standard, word, or expanded) #6 Make up your own examples and switch with a partner.
