Affirmation from Nathaniel
10 pages + 2-page answer key
"All students should be able to add numbers with one, two, or three digits, and ideally more. Eventually, all of my students can solve each problem on this worksheet in their head with 100% accuracy. Weaning them off the calculator can be difficult, but they love the speed with which they can add once they get the hang of it." -Nathaniel
