    New math:  65 - 27= 38
    You can solve many ways:  Subtract 2 tens from 65 because there
    are 2 tens in 27.  65-20=45  Then subtract 7 ones from 45 because
    there are 7 ones in 27. 45-7=38  38 is your answer!
     65= 60+5
    -27= 20+7
             40-2=38  you get a negative number when you subtract 5-7
     

    Example: 67 + 25 = __

    Place Value Strategy

    I broke both 67 and 25 into tens and ones. 6 tens plus 2 tens equals 8 tens. Then I added the ones. 7 ones plus 5 ones equals 12 ones. I then combined my tens and ones. 8 tens plus 12 ones equals 92.

    Counting On and Decomposing a Number Leading to Ten

    I wanted to start with 67 and then break 25 apart. I started with 67 and counted on to my next ten. 67 plus 3 gets me to 70. Then I added 2 more to get to 72. I then added my 20 and got to 92.

    Commutative Property

    I broke 67 and 25 into tens and ones so I had to add 60 + 7 + 20 + 5. I added 60 and 20 first to get 80. Then I added 7 to get 87. Then I added 5 more. My answer is 92.

     

    Students may solve this problem in a variety of ways. Examples are:

    50 - 12 

    50 – 10 is 40, then 40 – 2 is 38.

    50 – 2 is 48, them 48 – 10 is 38.

    You need 8 more to get to 20 from 12, then 30 more to get to 50, so the answer is 8 + 30 or 38.
    Note: Students who use this method are actually finding the difference between the two numbers
    and not simply "taking away." This is a wonderful opportunity to discuss different approaches to subtraction.

    99 + 17

    Students may solve this problem in a variety of ways. Examples are:99 and 1 more is 100, 100 + 17 is 117,
    but take 1 away that was added to the 99 to get 100, so the answer is 116.
    Some may attempt a traditional algorithm, but should notice that this is more cumbersome that examining
    the numbers and using the ideas above to compute.
     
     You can also use base ten blocks (models), number lines,  & 99 charts to show subtraction
    and addition.
