Dividing by 2-digit numbers can be a challenging task for students. However, with the incorporation of models, this concept can become more manageable. Models provide a visual representation of the problem, making it easier for students to understand and solve. Here are some activities that teachers can use to help students learn to divide by 2-digit numbers using models.

1. Draw the Problem:

Drawing the problem is one of the best ways for students to understand the concept of dividing by 2-digit numbers. Teachers can provide students with a variety of problems and ask them to draw the problem. This would help them visualize the problem and develop an understanding of how to solve it.

2. Use Base Ten Blocks:

Base Ten Blocks are a great visual representation of numbers. Use the blocks to help students understand the process of dividing by 2-digit numbers. For example, if you have 350 and you want to divide it by 25, you can show the students that 25 goes into 100 four times, and then you can demonstrate that each of those four pieces is 25, or one-fourth of the 100 blocks. This provides a foundation for students to see how to divide larger numbers.

3. Create a Flow Chart:

A flow chart is a simple but effective way to help students understand the process of dividing by 2-digit numbers. Start with a large number and work through the steps until you reach the final answer. Break the process down into smaller steps so that students can see how the problem is solved. A flow chart allows students to understand the logical progression of the process, one step at a time.

4. Use Manipulatives:

Manipulatives are another effective way to teach students to divide by 2-digit numbers. You can use unifix cubes or colored tiles to help students better understand the concept. For example, take 300 and cut it into 25 equal parts, each worth 12. Now subtract each part from 300 to arrive at the result of 12. This activity will help build a solid foundation for division by two-digit numbers, which is essential for many advanced-level mathematics topics.

5. Play a Game:

Games are always a great way to engage students and help them learn. Play division games with students that incorporate models, such as puzzles, memory matching games, or bingo with division problems. These games make learning fun and interactive.

In conclusion, division by 2-digit numbers can be a challenging concept for students but introducing different activities using models make it easier and understandable for them. Using visual aids, manipulatives, game-based learning, and other models to demonstrate the process of dividing by 2-digit numbers can provide students with a firm foundational understanding to develop their mathematical skills.
