A 40-minute mathematics block in a Class III–V multigrade room
You are the only teacher in a Class III–V room in a rural school in Baksa district. There are 47 children: 16 in Class III, 15 in Class IV and 16 in Class V. You have six periods a day and no second teacher or volunteer. The mathematics syllabus requires Class III subtraction with borrowing, Class IV two-digit multiplication, and Class V fractions. Your current practice is to teach one class at the board while the other two copy sums from the textbook. Last week's check showed that 11 of 16 Class III children still borrow from the wrong column, and 9 of 15 Class IV children cannot recall multiplication facts beyond 5. Class V children can shade fractions but cannot compare 2/3 and 3/5. You have one blackboard, a set of bottle caps, and 40 minutes for the mathematics period.
1. Design the 40-minute block so that all three classes get meaningful mathematics without copying as the default.

Use a three-part structure with teacher-anchored and independent segments. Minutes 0–10: whole-class number warm-up - oral counting, fact recall, and a quick comparison task using bottle caps, so all 47 are active. Minutes 10–25: teacher works intensively with Class III on borrowing using bundled sticks or caps (exchange ten ones for one ten), while Class IV does a self-checking multiplication grid and Class V works in pairs comparing fractions with folded paper strips. Minutes 25–35: rotate - teacher takes Class V on comparing 2/3 and 3/5 using equal-length strips, Class III does five graded borrowing sums with a partner check, Class IV does word problems using known facts. Minutes 35–40: whole-class close with two children explaining one answer. Reasoning: the copying default fails because it gives no feedback; the rotation guarantees every group gets direct teaching at least twice a week, and pair-checking uses the 47-child strength rather than treating it as a burden. Prepare the independent tasks on the board before the period.
2. How will you monitor learning when you cannot watch all three groups at once?

Build accountability into the task, not into your supervision. Use answer keys kept at the group table so pairs self-check and mark with a dot, not a tick, then record only errors on a class grid. Appoint rotating group monitors whose job is to explain, not to give answers. Collect one small product per group per week - a solved card, a fraction strip - and file it. Every Friday, spend the last 10 minutes of the day on a five-item diagnostic for one class only, so each class is checked fortnightly. Reasoning: with 47 children, monitoring must be sampled and systematic rather than constant; the grid tells you whether the borrowing error rate is falling, and the weekly product gives evidence for CCE records without extra periods.
