Subtraction with the Place Value Model

This lesson is the tradition model taught for subtraction of large numbers, by using place value. For example, 4 hundreds 5 tens and 9 one = 3 hundreds 15 tens and 9 ones. Children need a strong foundation of hundreds, tens and ones to be able to manipulate them for addition and/or subtraction. Click here to read my post on Rounding to Estimate Differences.

Using Place Value to Subtract Hands-On Lesson
1. Place large tubs of Base Ten Blocks in the middle of each group. We like to call it the BANK, I find when I relate most math lessons to money, for example... Take 4 hundreds to the BANK and return with only tens, their ears perk up a little bit more by relating it to money. {I then say something like... "When you use this math lesson to get a great job, please come by the old folks home and take me out to get ice cream!" :) :) :) }
2. Write some three digit numbers on the board, one at a time. Allow children time to get the exact amount of Base Ten Blocks from the bank.
3. Next, give them a three digit number, 627, allow them to get 6 hundreds, 2 tens and 7 ones. Then have them exchange 1 hundred at the BANK for 10 tens. Continue with more examples, having children in groups help each other and check each other's answers for more practice.
4. Finally, transition into 421 - 389 = Etc. and work these problems on the board and with the Base Ten Blocks together.

Don't have Base Ten Blocks? Read my post here about using other inexpensive items for hundreds, tens and ones.
