  1. Place Value http://www.youtube.com/watch?v=aTkW40v5USY&feature=related

  2. 4.NBT.1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 divided by 70 equals 10 by applying concepts of place value and division. • 4.NBT.2 Read and write multi-digit whole numbers using base ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meaning of the digits in each place, using <, >, and = symbols to record the results of comparisons.

  3. I can recognize a multi-digit number in one place represents ten times what it represents in the place to its right.

  4. How does a digit’s position affect it’s value? • http://www.youtube.com/watch?v=npx98CWJp9Y • Activity: Base Ten Relationship • Place Value mat and base ten blocks • Math in Focus CD • What is the relationship (10 times)

  5. Let’s Practice • http://ca.ixl.com/math/grade-4/convert-between-place-values

  6. Formative Assessment • What is the relationship between 7 tens and 7 hundreds? • What is ten tens? Homework WB PG 1-2

  7. I can identify place value to Millions. http://www.youtube.com/watch?v=qJJugG1bTf4

  8. Use the SMART identify place value activity to name every place value spot through millions. Place Value to the Millions worksheet/arrow cards (if needed).

  9. Formative Assessment On a Post-it – What digit is in the ten thousands place in the following number: 1,365,098

  10. I can read and write multi- digit whole numbers using base ten numerals.

  11. SMART activity to learn to read and write numbers using Building and Reading Numbers activity. Activity: Read numbers to students and have them read/write down numberson white boards using the Power Point presentation to display numbers.

  12. Formative Assessment Listen to your teacher as she says a number and then write the number on your post-it. Place post-it on response grid.

  13. I can read and write multi-digit whole numbers using number names/words. I can read and write multi-digit whole numbers using expanded form. http://www.youtube.com/watch?v=uBuofv6Bbn0

  14. Use identify value SMART activity to introduce expanded form. • Use arrow cards to practice building numbers and take them apart to write in expanded form. • Class discussion on the difference in place value and value. Place value is the name of the place and value is what the digit is actually worth.

  15. Which of the following is the correct way to write 23,908?... • Two ten thousand, nine hundred eighty • Twenty three thousand, nine hundred eight • Twenty three thousand, nine hundred eighty • Twenty three ten thousand, nine hundred zero eight.

  16. Centers Day • You will rotate through the following Centers: • Double Trouble Folder Game • Place Value Number Battle • Number Word and Expanded Folder Game • Place Value Puzzle • Computer

  17. Place Value Number Battle Directions/Student Activities: Players split a deck of cards and simultaneously flip over their top 3 cards to create a 3-digit number. Players may move the cards and place in any position of the number they wish. The highest number wins all six cards.

  18. Formative Assessment:Which of the following is the expanded form of 45,984? • 40,000 + 5,000 + 900 + 84 • 40,000 + 5,000 + 90 + 80 + 4 • 40,000 + 5,000 + 900 + 80 + 4 • 45,000 + 900 + 80 + 4 Homework: Math in Focus pg. 6

  19. I can compare two multi- digit numbers based on the meanings of digit in each place using symbols.

  20. SMART activity Pearsons Comparing Numbers • Student workbook page on comparing numbers

  21. SMART activity on place value with dice • .

  22. Activity • Students will work in pairs to create numbers with playing cards trying to build the greatest number. Students will record their numbers and comparison symbols

  23. Homework • Math In focus pg.7-8

  24. Which comparison symbol goes in the blank 54,987 ____55,870? • < • > • = • +

  25. Formative Assessment: Compare the following numbers:87, 098 ______8,798 • > • < • = • +

  26. Compare 987,098 ___ 987, 980 • < • > • + • =

  27. Compare 17, 983 ____ 71, 983 • < • > • + • =

  28. I can use place value understanding to round multi-digit numbers to any place. http://www.youtube.com/watch?v=3afU6JQG15I&feature=related http://www.youtube.com/watch?v=OVmYl3x85j4&feature=related

  29. SMART activity on rounding using a number line • Create a number line with students as 1,000; 2,000; etc. and then give the rest of the class numbers and have them position themselves to the nearest thousand.

  30. SMART activity Rounding Numbers • Activity with partner: Playing cards to create 5 digit numbers, rounding to the nearest ten, hundred, thousand, and ten thousand.

  31. Round the following number to the nearest ten thousand: 76,098 • 70,000 • 80,000 • 76,000 • 77,000

  32. Round the following number to the nearest hundred thousand: 939,098 • 900,000 • 940,000 • 1,000,000 • 930,000

  33. Round to the nearest thousand: 453,985 • 500,000 • 450,000 • 453,000 • 454,000

  34. Round 78,990 to the nearest hundred. • 79,000 • 80,000 • 78,900 • 78,000

  35. Round to the nearest thousand76,403 • 77,000 • 80,000 • 76,000 • 70,000
