In Prime Time students will explore certain important properties of whole numbers, especially those related to multiplication and division. The investigations in this unit will help students to:
- Understand relationships among factors, multiples, divisors, and products;
- Recognize and use properties of prime and composite numbers, even and odd numbers, and square numbers;
- Use rectangles to represent the factor pairs of numbers;
- Develop strategies for finding factors and multiples, least common multiples, and greatest common factors;
- Recognize and use the fact that every whole number can be written in exactly one way as a product of prime numbers;
- Use factors and multiples to solve problems and to explain some numerical facts of everyday life; and
- Develop a variety of strategies for solving problems building models, making lists and tables, drawing diagrams, and solving simpler problems.
