Interactive Lesson – Iterative Simple Division's image
Description: This clip shows a teacher in Zambia of 2nd grade students using an interactive method to review simple division problems. The students have previously been taught division, so this activity is a way to engage them and review. The activity proposes a division problem with one known number, in this case a 2, and two unknowns. The class works together through the problem, proposing numbers to fit the two unknowns to make the division statement true.

Abstract: This clip shows a teacher in Zambia of 2nd grade students using an interactive method to review simple division problems. The students have previously been taught division, so this activity is a way to engage them and review. The activity proposes a division problem with one known number, in this case a 2, and two unknowns. The class works together through the problem, proposing numbers to fit the two unknowns to make the division statement true.

The teacher allows the students to propose incorrect numbers and work out why they are wrong, and at one point brings in sticks to help demonstrate why one combination of numbers cannot work. Though the process takes more time then waiting for someone to come up with the right answer, or even giving the right answer away, it involves the whole class and ideally emulates the process each learner might go through if given the problem individually.
