Why only one rectangle can be build with a prime number of a square tiles?
Because prime numbers only have one factor pair.
How can you use an array of counters to identify whether a number of counters is prime or composite?
If you can arrange the counters in the shape of a rectangle with at least two in each row and each column then the number is composite. The numbers of row and the numbers of columns are factors of the given number. If the only rectangle you can make is the "degenerate" one, with only one row or only one column, then the number is prime.
Using from 2 to 30 cubes how many numbers can you find that will allow you to make only one rectangle?
2 3 5 7 11 13 17 19 23 29
What are numbers that have only two factors?
Prime numbers only have one and itself as factors.
What numbers have only one prime factor?
Prime numbers.
What are some numbers that can be made into only one rectangle?
Any prime can be made into only one rectangle. Any composite number can always be made into at least two different rectangles.
There are some numbers that can be made into only one rectangle?
1, 3, 5,9
Why only one rectangle can be build with a prime number of a square tiles?

What kind of numbers can make one rectangle?
prime numbers
There are some numbers that can be made into only one rectangle Find all of these numbers up to 50?
Those would be the prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47

How do you find rectangles using the prime numbers?
Prime numbers have one factor pair, hence one rectangle.
Which numbers have the most rectangle and what kind of numbers are these?
Composite numbers have the most rectangles. These numers are numbers that have factors other than their self or one
How can making rectangles from units help define and identify prime and composite numbers?
If you can make more than one rectangle, it's a composite number. If you can only make one, it's prime.
What number of tiles will make only one rectangle?
1
What is the answer of not a characteristic of a rectangle?
Only three sides is one possible answer.
What numbers up to 50 can make only one rectangle?
Those would be the prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47
