Introduction/Focus:
• Do you remember talking about GPAs for seniors
from yesterday?
• Well, guess what?
• The GPA must be taken to the nearest thousandth
place in some cases in order to get the grades in an
order. So, we must be able to order decimal
numbers also.
Guided Practice: (DOK 1 and 2)
• Ordering Decimals
• Note: (3.45 should be “three and forty-five
hundredths” not “three point forty-five”).
2.123
2.167
2.129
• “How can we tell which of these decimal
amounts is the largest?”
2.123 2.167 2.129
• 1) Align the numbers on top of each other making
sure that the decimal points are aligned:
• 2.123
• 2.167
• 2.129
• Therefore, the numbers in order from greatest to
least are: 2.167, 2.129, and 2.123
Order these from least to greatest
(ascending)
• 3.672, 3.521, and 2.670
• 46.907, 46.970, and 4.690
Order these from greatest to least
(descending)
• 0.076, 0.76, 0.7, and 0.06
• 3.134, 3.218, and 3.135
Ordering Activity:
• Groups of four.
• 1 sheet of blank paper.
• Write a nine-digit number (including a decimal) of
your choice on the paper and immediately turn it
over on your desk. When I say “go,” you must
work together to place yourselves either in
ascending or descending order.
• Each team then passes its numbers to another
group, and the teams must work again to order
themselves correctly.
Independent Practice/Activities:
• Clothesline Game – String a clothesline (with
clothespins)
• You will have a total of five minutes to put
yourselves in order from least to greatest!
• WITHOUT TALKING!!!
Closure:
• 432.233
432.322
432.320
• Put these numbers in ascending order.
