Sub-goal A: Solve addition tasks with items available
Using items to solve addition tasks initially involves counting from one, by ones. The total for two collections of items can be found by associating each number word in sequence with one, and only one, item. The last number word in the count tells how many. The instructional resources provide opportunities to engage students in counting to add two visible collections.
