We began partial sums this week. I sent home sheet explaining this method on Curriculum Night, but your children should also be coming home with examples of the "Partial Sums" addition method today to show you what we've been doing in class. It is very different from how we learned addition, but the students do benefit from solving multiple digit addition problems using this strategy.
Below is a Everyday Math video on how to solve addition problems using partial sums. The only difference is that in the video, they added the hundreds first, then the tens, then the ones. We do partial sums by adding the ones, then the tens, then the hundreds, and then adding the numbers all together.
Please feel free to contact me with any questions. Happy adding! :o)
