  • Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones.
    • This connects to the Partial Sums Algorithm because...
      1. It has students breaking down big numbers and separating them by their place values.
      2. After that, they simply add the hundreds #, the tens #, and the ones #, rather than two complex numbers as a whole.
      3. Finally, they add the sums of all of the broken down numbers to get an answer.
    • The purpose of this alternative algorithm is to break it down and get easier numbers to add with.

They're both set up vertically and are added. The "1" is carried over when the value go beyond 9 and into the next place value. Standard Algorithm has us adding the numbers as they are. This can be challenging for students if the numbers start getting bigger. That is why it is important to be able to use Partial Sums as an algorithm for students to follow. This way, they can break up numbers, such as "38,249" into 30,000, 8,000, 200, 40 & 9 and add it to "X" and its respective partial sums. The two algorithms connect when you realize that everything is the same, aside from breaking apart the numbers for Partial Sums.]]> 2017-03-07 19:34:54 UTC https://padlet.com/yang_charlie/addition/wish/158475399 How It Works yang_charlie https://padlet.com/yang_charlie/addition/wish/158475568 A video of Me explaining Partial Sums:

Sum: The total amount resulting from the addition of two or more numbers.
Place Value: The numerical value that a digit has by virtue of its position in a number.
Hundreds: Regarding to the numbers in hundreds place.
Tens: Regarding to the numbers in the tens place.
Ones: Regarding to the numbers in the ones place.]]> 2017-03-08 00:49:21 UTC https://padlet.com/yang_charlie/addition/wish/158533555
