Partial Sum Method for Teaching Double Digit Addition (with and without regrouping)

You might remember my recent post about double digit addition using the decomposition method. Well, today I’m excited to share another method you may or may not have heard of to teach addition.

PARTIAL SUM!

This method might be the easiest to understand and master. It makes me a little jealous that I wasn’t taught methods like this when I was in elementary school. I remember carrying over the one to the tens place in regrouping, but not REALLY knowing what that meant for the longest time.

Partial sum addition really helps conceptualize the whole idea of addition. This method especially helps my struggling math students understand numbers better and improve their addition skills.

I created this pack to help introduce, teach and assess double digit addition with and without regrouping using the partial sum method. Included in this pack is: mini anchor charts/posters, a sort, 4 practice sheets and answer keys, 2 assessments (with and without regrouping) and answer keys.

Let me know if you love this method as much as I do!
