This math topic focuses on introductory long division problems where learners practice dividing a total number of items (riders) by a given count of groups (cars or buses) to determine how many items belong to each group, while initially ignoring the remainder. Problems involve simple division calculations with 1-digit divisors, providing fundamental division skills and the concept of distributing quantities evenly among groups. This is a basic step in learning long division, incorporating real-life scenarios like dividing people into vehicles. Each question offers a practical example to help solidify learners' understanding of division without remainders.
