Topic 1
By: Emily Gabrisch

8. Numeration
This slide show will review for you how numbers are formed, and how to compare and order whole numbers.
You will also see questions throughout and they are numbered. You will write the answers down on a piece of paper and we will check them as we go through the activities.

9. What we will learn: Numerals and digits Place Value
Comparing and Ordering Whole Numbers

10. New Vocabulary
Digits
PlaceValue
Standard Form
Expanded Form
Word Form

11. New Vocabulary Definitions
Digits – The digits 0,1,2,3,4,5,6,7,8,9 are used to write numbers.
PlaceValue – The place of a digit in a number tells you its value.
Standard Form – 1,600,000
Expanded Form – 1,000, ,000
Word Form – One million, six hundred thousand
Period – the group of ones, tens and hundreds for each place value.

12. Review Digits, period, place value, whole numbers
6. 10,000+2, = On to Numeration System
Choose from the above 4 words to finish these sentences. 1. ____ are the symbols used to show numbers. 2. A group of 3 digits in a number is a _____. 3. _____ is the position of a digit in a number that is used to determine the value of a digit = =

13. Numeration System???
A numeration system is a system or plan for naming numbers.
It uses the digits 0 through 9.
It uses groups of 10.
The position to the left is 10 times the position to it’s right. This is called a base ten numeration system.

14. Video
Now we will view a video on place value of whole numbers. After the video is over, we will practice working on place values.

15. Place value
To write numbers, we use any one of the ten digits in any place value. Example:
432 has a 4 in the hundreds place, a 3 in
the tens place, and a 2 in the ones place.
Here is place value chart for a large number.

20. Comparing and Ordering Whole Numbers
Comparing and ordering whole numbers are important to understand. You need to know which numbers are smaller or larger. The way you can do this is by understanding the VALUE of each digit in their respective places.

21. Video
Now we will view a video on comparing and ordering whole numbers. After the video is over, we will practice comparing and ordering some whole numbers.

22. Understand???
20. Put these numbers in order: 262, 280, , 247, 293, 263
21. Put these numbers in order: 999, 878, 901, 109, 199, 888
<,> or =
___877
___626
___351

10. 9,033 ___ 9,133
11. 1,338 ___ 1,388
12. 7,325 ___ 7,321
13. In the number 767, does the first 7 have the same value as the final 7? Why or why not?

24. Practice with ordering
Order the following numbers from least to greatest on your own paper. 8493, 7438, 63662, 93923, 1343, 4892 ______________________________________ 345, 7839, 67, 229, 4589, 42 _______________________________________

25. More Practice with ordering
Order the following numbers from greatest to least on your own paper. 8493, 7438, 63662, 93923, 1343, 4892 ______________________________________ 345, 7839, 67, 229, 4589, 42 _______________________________________

26. What we have learned Digits are put in place values to write numbers.
Place value determines the value of a digit.
We can compare whole numbers using the signs > greater than, < less than and = equal to.
We can order numbers by comparing their place values and digits.
