The focus of the first-grade activity with cubes is to help students understand different number pairs that sum to a specific total, in this case, the number 7. By manipulating cubes, students can visually and physically engage with numbers, discovering that there are various combinations, such as 1 and 6, 2 and 5, or 3 and 4, that add up to 7. This foundational understanding of addition and number relationships is crucial for developing mathematical reasoning.

Students are not merely identifying quantities in a set or learning to recognize the number of items, which is more aligned with basic counting skills. Showing conservation of numbers involves understanding that quantity remains the same despite changes in arrangement or order, which can be a separate conceptual area. Comparing numbers typically involves understanding greater than or less than relationships, which is also distinct from the activity focused on number pairs. Overall, the activity utilizes hands-on manipulation of cubes to foster an understanding of how different numbers can combine to create a total, making option A the most appropriate choice regarding the learning objective.
