Place Value

Haley Hlad

what is it?

The place of a number in a multi digit number that determines the value.

using the same numbers

Multi digit numbers that use the same numbers in a different order are not the same value.
ex. 145 and 154: How are they the same and how are they different?
ex. 5: How does changing the place value of the number 5 change the value of the number?

place value base 10

Adding on to the previous place value information, looking at larger numbers base 10 works from ones, to tens, to hundreds, to thousands, and so on. Students are able to identify which number is in which place.
ex. 1829: What is the name of the place the number 8 is in?
ex. 6243: Which number is in the thousands place?
