Teaching Addition with Regrouping
What it is
Eight three-digit sums with regrouping, a code key that turns each answer into a letter, a short message to decode, and two sentences to write about what the message means.
When a child is ready
Ready once three-digit addition is worked accurately on paper.
If they struggle
Match each answer to the key before moving on. An answer that is not in the key means a carried digit was missed.
