Expand addition concepts by challenging your pupils with these multi-digit addends. They add up numbers with up to seven digits, regrouping where needed. The first six are written vertically and the next two are horizontal. Make expectations clear on whether or not scholars can rewrite the horizontally number sentences. Three more addition problems have mathematicians fill in missing numbers in the addends to complete equation. Finally, they apply these skills to solve a word problem, showing their work in the space provided. Remind kids to add those commas!
