Description - To enable students to develop strong numerical abilities and fundamentals without loss in instructional time, give students opportunities for differentiated practice during non-classroom hours. 1. Write simple multiplication and division problems on the board. 2. Keep a maths box in class. 3. Students have to solve these problems in their free time and deposit the answers into the maths box whenever they finish. 4. Check the submitted answers and guide students who are still making errors. 5. As proficiency increases, give students tougher sums. Differentiated instruction is a learner-centred methodology that enables students to learn at their own pace. While different students progress at different speeds, the difficulty levels of the problems increase in steps since the entire group of students has to solve the same problems.
