Ms. Miles & Ms. Connelly Subtraction With Regrouping

HundredsTensOnes == 1 one hundred equals? 10 tens 10 tens equal? 10 ones

Ones 286 Let’s model 286 minus 119. Begin by showing HundredsTens

If you have 6 ones, can you take away 9 ones? HundredsTensOnes

How can you get more ones? You can trade 1 ten for 10 ones! HundredsTensOnes

Hundreds Tens Ones How many tens and ones now? 716

Hundreds Tens Ones What’s the next step? How many ones are left?

Hundreds Tens Ones What’s the next step? How many tens are left? 6

Hundreds Tens Ones Let’s model 203 minus 157. Begin by showing 203.

Hundreds Tens Ones If you have 3 ones, can you take 7 ones away?

Hundreds Tens Ones If 10 tens are in one hundred, how many tens are in two hundreds? 10 tens + 10 tens = ? tens

Hundreds Tens Ones Can you trade 1 of the 20 tens for ones? How many tens are left? 20 tens - 1 ten = ? tens

Hundreds Tens Ones That’s 19 tens left 19 tens 19 which is the same as 1 hundred and 9 tens.

Hundreds Tens Ones This means we can trade for ones. How many ones do you have now? 1913

Hundreds Tens Ones What is 13 ones minus 7 ones?
