  1. Purpose: I can identify how place value relationships relate to each other- please write this down! 3-2

  2. You know about representing numbers in the place-value system and the names of each place. Today you are going to look more closely at those places and see how they relate to each other.

  3. In the number 1,234, what is the value of each of the digits?

  4. In the number 770, what is the relationship between the value of the first 7 and the value of the second 7?

  5. What do you notice about the numbers 700 and 70 in : 770? How are they related?

  6. What do you notice about the numbers 700 and 70 in : 770? How are they related? • The value of the first 7 is ten times as much as the value of the second 7. Let’s look at another number…

  7. In the number 3,300, what is the relationship between the value of the first 3 and the second 3?

  8. In the number 3,554, does having a 3 in the thousands place and a 4 in the ones place change the relationship between the values of the two 5’s?

  9. No, the 5 in the hundreds place is still 10 times as great as the 5 in the tens place.

  10. Example: The number 110 • The first one is in the hundreds place. Its value is 100. • The second one is in the tens place. Its value is 10. • How is 100 related to 10?

  11. How is 100 related to 10? • 100 is ten times as much as 10. The first 1 is worth ten times as much as the second 1! • When two digits are next to each other in a number are the same, the digit on the left is ALWAYS ten times as great as the digit on the right!

  12. Practice: Pages 68-69 numbers 1-32 • Refer to your notes if you get stuck! • Early finishers: Find the value of each digit in the number: 553,322 • How are the relationships of the 5s, 3,s and 2s similar? • CHECK WORK, CHECK IN WITH ME, THEN PROBLEM SOLVE.
