Adding Big Numbers Word Problems
Learning Objective
I can solve 7-digit addition word problems with regrouping.
Key Concepts
Regrouping is changing the way an amount is grouped while keeping the total value the same.
The addition algorithm is a step-by-step process for adding multi-digit numbers, lining up the addends in place value order.
When using the subtraction algorithm, keep regrouping as needed, subtracting, and moving to the next place until you find the difference.
