This app introduces students to prime numbers. Each button connects a student to a prime number exploration. While there are an infinite number of prime numbers, this app limits students to those less than 1,000,000.
Is It Prime - allows a student to enter a single number and then find if that number is prime or composite when the pump button is pressed.
The Next Prime - allows a student to enter a single number and then find the next prime number larger than that number. Each successive press of the pump yields the next prime in the sequence. You must press start over to start a new sequence. Otherwise, it continues the current sequence even after you enter a new starting number in the input box.
Primes Between - allows a student to enter a number and then count and find all of the primes in the next 1000 numbers when the pump button is pressed. Press the pump only once and wait for the app to generate your list. Pressing multiple times will result in the app repeating the same list once for each button press.
Random Prime - allows a student to enter an upper limit and find a new random prime number between 1 and the upper limit when the pump is pressed.
About Primes - provides links to websites with information about prime numbers.
Prime History - provides links to sites that explore the history of how humankind explored prime numbers.
