Summary: When teaching students how to regroup, sometimes it's about concept attainment and that means doing various problems using the same strategies. When we add using regrouping it's often faster and easier to show them simultaneously instead of taking time after time designing and dragging our base-ten models onto the place value chart. So the geniuses at E-Labs have created a "calculator" that shows how regrouping is done. You can add up to three digits and click the "regroup" button to see how numbers are regrouped.
