This number of tiles will make only one rectangle?
Assuming that you are asking about a rectangular or square tile, the answer is one--Squares are rectangles with sides of equal lenght.
How is making rectangles from square tiles help you define and identify prime numbers and composite?
Jennifer has made a rectangle using 48 square tiles If she adds the length and width of her rectangle together she gets a prime number What is the length and width of Jennifer's rectangle Explain?
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 all five tiles, only one rectangle can be made. (1 tile wide by 5 tiles long) Using less than all five tiles, you could make six different rectangles. (squares are technically rectangles too.) The rectangles possible would be: 1 tile wide by 5 tiles long, 1 wide by four long, 1 wide by 3 long, 1 wide by 2 long, 1 wide by 1 long, and 2 wide by 2 long.
To exchange tiles: *Place the tiles you wish to exchange face down on the table, and announce how many tiles you are exchanging (e.g. "Exchange five"). *Start your opponent's timer (if you are playing timed). *Draw the desired number of tiles to replenish your rack (e.g. five in this case) and place them on your rack. *Put the face-down tiles into the bag. Note that you can only exchange when there are at least seven…
