Teaching the concept of dividing by 2-digit numbers can be challenging for students. However, by using partial quotients, the process can be made simpler, allowing students to learn the concept efficiently. In this article, we will explore some activities to teach students to divide by 2-digit numbers using partial quotients.
Activity 1: Building Blocks Method
This activity involves using blocks to visually represent dividing by 2-digit numbers. For this, give each student a pile of blocks. Then, give them a 2-digit number to divide by. Start by asking them to divide it by 10, which is the first building block. Next, ask them to divide the number by the second building block, which is 1. Students can see the connection between the two blocks and understand that dividing by the first block reduces the number by 10 times, while dividing by the second block reduces it by only one.
Activity 2: Partial Quotients Method
This activity involves using the partial quotients method to teach the concept of division. Start by teaching them how to use partial quotients and then give them a series of questions to practice on.
For instance, if the question is 312 divided by 24, the partial quotient method involves dividing 24 into 30 (one partial quotient) and then subtracting the product of 24 multiplied by one (24) from 312, which gives 288. Next, divide 24 into 288 (the second partial quotient is 12) and subtract 24 multiplied by 12 (288) from 288, which leaves zero. This means that the final answer is 13.
Activity 3: Model Drawing
This activity involves using a pictorial representation of the division process. Start by giving students a problem to solve, like 582 divided by 24. Students should then use model drawing to visually represent the division process, making use of blocks to serve as the model.
Divide the blocks into groups of twos, fours, eights, and sixteens, and then write the partial quotients and the remainder each time. For example, 24 goes into 58 twice, with a remainder of 10. Then, 24 goes into 1024 times, which gives another remainder of 10. Finally, 24 goes into 108 twice, with a remainder of 0.
Conclusion:
Teaching the concept of dividing by 2-digit numbers using partial quotients can be a challenging task. Nevertheless, by using activities such as the ones mentioned above, you can make it simpler and increase student understanding and engagement. Furthermore, these activities can bring a fun element to the lesson, making the learning process enjoyable and more memorable.
