This math topic focuses on division problems where students must determine the remainder after dividing a set number of items (cards) among a specified number of recipients (players). Specifically, it challenges students to divide two-digit numbers by one-digit numbers and calculate the leftover items. Each problem presents a scenario with a different number of cards and players, and asks how many cards remain after distribution. The problems are framed within a context of dealing cards to players, blending basic arithmetic division with practical application to deepen understanding of remainders.
