  5. Place Value Number Sense and Theory Lesson Objective: Read and write numbers from millions to millionths in various contexts. (spi 506.2.1)

  6. Here are the different ways to write a number: • Standard Form: 529 uses only digits • Short Word Form: 5hundred29 uses digits and words • Word Form: five hundredtwenty-nine uses only words • Expanded Form: 500 + 20 + 9 uses digits to show the value of each place

  7. Place Value Read and Write numbers from millions  millionths Word Form: 1,045 one thousand forty-five six hundred two 602

  8. Place Value cont. • Write numbers in e x p a n d e d form: 6,097,133 6,000,000 + 90,000 + 7,000 + 100 + 30 + 3 5,014 = 5,000 + 10 + 4

  9. Place Value cont. Short Word Form 83,903 = 83 thousand, 903 7, 062= 7 thousand, 62 Why is there not a 0 in this answer?

  10. Place Value • Identify the place value of a given digit: What place is the 2 in each of these #s ? 6,200,799 484,102 25,361,969 125,007 528

  11. Place Value • Identify the place value of a given digit: What place is the 2 in each of these #s ? 6,200,799 hundred thousands 484,102ones 25,361,969 ten millions 125,007 tenthousands 528tens

  13. Comparing and Ordering Whole Numbers Lesson Objective: Compare whole numbers using the symbols <, >, and =. (spi 506.2.9)

  14. Comparing Numbers Compare 9,430,987 and 9,428,987 Step 1: Write the numbers in a vertical list. Line up the numbers by place value. 9,430,987 9,428,987

  15. Comparing Numbers Step 1: Write the numbers in a vertical list. Line up the numbers by place value. 9,430,987 9,428,987 Step 2: If the numbers have the same number of digits, start from the left and compare digits one at a time. **Notice the different digits in the ten thousands place. Since 3 is greater than 2…. 9,430,987 > 9,428,987 greater than

  18. Ordering Numbers Order 19,475; 18,338; and 18,358 from greatest to least Step 1: Write the numbers in a vertical list. Line up the numbers by place value 19,475 18,338 18,358

  19. Ordering Numbers Order 19,475, 18,338, and 18,358 from greatest to least Step 1: Write the numbers in a vertical list. Line up the numbers by place value Step 2: Start from the left and compare each digit 19,475 18,338 18,358

  20. Ordering Numbers Order 19,475, 18,338, and 18,358 from greatest to least Step 1: Write the numbers in a vertical list. Line up the numbers by place value Step 2: Start from the left and compare each digit 19,475 18,338 18,358 From greatest to least: 19,475 > 18,358 > 18,338

  21. Label paper: POD 1-3 (date) **Write answers in a complete sentence.

  22. Sample answer…sentences may vary. Cream of celery and turkey vegetable need to be restocked.

  23. Place Valuewith decimals through millionths Lesson Objective: Read and write numbers from millions to millionths in various contexts. (spi 506.2.1)

  24. Starting with the ones place, let’s name the places together, in order, from ones to millions: ones tens hundreds thousands ten thousands hundred thousands millions

  25. Starting at the decimal point, • the places are named in the • same order except: • there is not a “ones” place • all names end in “ths” to • signify that it is a decimal ones tens hundreds thousands ten thousands hundred thousands millions (.) decimal tenths hundredths thousandths ten thousandths hundred thousandths millionths
