Student Counting and Comparison

The video tutorial explains how to compare the number of students in Janet's first and second grade classes. It uses a visual method by drawing Xs to represent students, showing 35 students in first grade and 23 in second grade. The tutorial then demonstrates how to find the difference by subtracting the number of students in second grade from those in first grade, resulting in 12 more students in the first grade. The process is explained step-by-step, emphasizing visualization and basic subtraction.
