Numeration Topic 1 By: Emily Gabrisch
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.
What we will learn: Numerals and digits Place Value Comparing and Ordering Whole Numbers
New Vocabulary • Digits • PlaceValue • Standard Form • Expanded Form • Word Form
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 + 600,000 • Word Form – One million, six hundred thousand • Period – the group of ones, tens and hundreds for each place value.
Review Digits, period, place value, whole numbers 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. 4. 800+90+2 = 5. 3000+400+50= 6. 10,000+2,000+60+1= 7. 37+85 8. 124+76 On to Numeration System
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.
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.
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.
Example of Place Value Example
Practice • 14. Write the number two hundred sixty five thousand, four hundred thirty seven in standard form. • Write the number five hundred four thousand, six hundred twenty in standard form. • Practice More!
Practice 16. Write the number 68,235 in word form. 17. Write the number 792,198 in word form.
Practice • 18. Write the number 704,630 in expanded form. • 19. Write the number 92,308 in expanded form.
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.
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.
Understand??? 20. Put these numbers in order: 262, 280, 222, 247, 293, 263 21. Put these numbers in order: 999, 878, 901, 109, 199, 888 <,> or = 22. 787___877 23. 636___626 24. 459___351 25. 566___723 Decimal Place Value Back to main menu?
More Practice with comparing Use <,> or = 9. 869 ___912 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?
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 _______________________________________
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 _______________________________________
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.
