📌 Explanation Summary:
This worksheet teaches
addition with regrouping (carrying). The key idea is:
- When the sum of the ones column is
10 or more, you
carry over the tens digit to the tens column.
- You write the
tens part in the box and the
ones part under the ones column.
- Then add all the tens together, including the carried ten.
This builds foundational skills for multi-digit addition.
