Teaching division strategies can be challenging for teachers, but engaging activities make the task a lot easier. When it comes to division by 9, students might struggle to master the concept, but with fun and interactive lessons, they can quickly grasp the concept and avoid mistakes. Here are some activities to teach students to divide by 9.

1. The “finger count” strategy

The finger count strategy is a fun and engaging way for students to learn to divide by 9. First, show them how to count fingers in multiples of 9 from 0 to 9 (0, 9, 18, 27, 36, 45, 54, 63, 72, 81). Next, ask the students to choose a number to divide by 9 (e.g., 54). Then, they need to count the number of fingers from 0 to the number they have chosen. This will give them the quotient and the remainder if any.

2. The “subtract 10” strategy

Another way to teach division by 9 is the “subtract 10” strategy. First, pick any number to divide by 9 (e.g., 45). Then, take away 10, which leaves 35. Next, divide 35 by 9, which gives the answer with the remainder. Finally, add the quotient from the second step to the quotient from the first step to get the final answer.

3. The “multiplication by 1/9” strategy

This strategy involves teaching students to multiply by 1/9. First, show them how to divide 1 by 9, which gives the decimal equivalent (i.e., 0.111…). Next, ask the students to divide the number they have chosen by 9, and then multiply it by the decimal equivalent of 1/9. This gives the quotient and the remainder, if any.

4. The “visual” strategy

Another way to teach division by 9 is by using a visual aid. First, draw a circle divided into 9 equal parts, and label each part with a number from 1 to 9. Next, ask the students to select a number to divide by 9. Then, ask them to count the number of parts in the circle corresponding to the selected number. The count gives the quotient and the remainder, if any.

In conclusion, teaching division by 9 can be a fun and engaging experience for students. Teachers can use different strategies such as finger counting, subtracting 10, multiplication by 1/9, and visual aids to help students master the concept. These activities will make the process of learning division by 9 not only easier but also enjoyable.
