# Activities to Teach Students Prime and Composite: Up to 20

Prime and composite numbers are two fundamental concepts in mathematics. They are elementary, and students need to learn them early on to comprehend more advanced concepts. Prime numbers are those that can only be divided by themselves and one, while composite numbers can be divided by more than just themselves and one. Creatively teaching prime and composite numbers using activities is crucial to engage students in the learning process while maintaining their interest in the subject. Here are some exciting activities that teachers can use to teach students prime and composite numbers up to 20.

1. Prime or Composite Dice Game

Teacher or students would need to make two dice. One dice would have numbers from two to nine, while the other die would have prime or composite written on it. Students then roll both dice and have to identify whethere their number is prime or composite. The teacher checks the answer, and if it’s correct, the student receives a point. The first student to get to ten points wins the game. Besides, dice can be easily made by hand or using printables found online, making it a cost-effective and straightforward activity.

2. Number Chip Arrays Game

Students will need a bag of counters or chips. They pick a prime or composite number from a hat and use the counters to create a grid of that many squares. Then they must determine whether they can make a rectangle with the same number of squares. If they can, the chosen number is a composite number; otherwise, it is a prime number. This game can be made competitive by making it a game of speed to see which student can identify the prime or composite number the quickest.

3. Prime and Composite Numbers Maze

A maze game is an excellent activity to help teach prime and composite numbers. The maze begins at number one, and students must chart their way through prime numbers, which lead to the finish line. However, incorrect paths that lead to composite numbers keep sending them back to the beginning of the maze. Such an activity is a fun way to teach students about prime and composite numbers, and students enjoy competing with each other to see who can get through the maze the fastest.

4. Prime and Composite Numbers Bingo

A classic game that kids love is bingo. For this activity, students need to make a prime and composite number bingo card that includes numbers from one to 20. The bingo caller then calls out only prime or composite numbers, and students must cross them off on their cards. The first student to cross all their numbers wins the game.

5. Prime and Composite Numbers Chart

Creating a prime and composite numbers chart is a quick and easy activity for students of all ages. The chart includes the numbers from one to 20, and students need to figure out if each number is prime or composite. The chart can be used as a reference point during class discussions or activities throughout the school year.

In conclusion, activities are essential in helping students learn and understand prime and composite numbers. Teachers need to be creative and come up with fun and challenging activities that keep students engaged while they learn. Implementing such activities makes it easier for students to understand and retain what they learn about prime and composite numbers. As a result, they become more confident in their mathematical skills and eager to learn more.
