Adding Lists of Numbers

Practice adding lists of numbers

These problems have students adding a long list of numbers. A common strategy that students use to make this task easier is to find combinations of values in each column that add up to ten. You can adjust how often ten-combinations appear in the set of numbers by setting the Ease of Grouping control in the form. You can also set ranges for the number of addends in the list and the number of digits in each addend.
