This math topic focuses on practicing division through skip counting, specifically aiming to determine the number of items based on a total count of their collective sub-parts (like legs of chairs or cows). Each problem asks students to find the number of items, such as chairs or cows, that would collectively have a specified number of legs if counted by fours. Understanding and applying skip counting in the context of division is a key skill reinforced throughout these problems. The exercises are presented in a multiple-choice format, reinforcing both division and multiplication skills.
