A teacher leads a classroom through arithmetic worksheets covering addition, subtraction, multiplication, and division. Students work through a four-digit number divided by a two-digit divisor and practice mental division. The teacher walks through step-by-step calculations, checks understanding, and collects notebooks for correction.
