Game: DUCK SHOOT

Method:
Use the catapult to shoot balls at the rows of ducks crossing the screen. Answer questions to win extra points.
Your final score is based on ducks hit or missed and the number of questions answered correctly.
4th grade / Multiply + Divide / Prime factors / Prime factors
Prime numbers are special numbers that can only be divided by 1 and the number itself without leaving a remainder. In other words, they have exactly two factors. So the number 3 is a prime number because it is divisible only by 3 and 1. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, and 19. Many numbers are not prime, they are composite numbers - numbers that have more than two factors. These numbers can be divided by different numbers, not just 1 and themselves. For example, 4 can be divided by 1, 2, and 4.
Prime factorization is a way to break down a composite number into smaller pieces that are all prime numbers. These smaller prime numbers are called "prime factors". To work out the prime factors of a number, start with the smallest prime number, 2, and see if it divides the given number without leaving a remainder. If it does, write down the number 2 and the result of the division. If it doesn't, move on to the next smallest prime number, 3, and try again. Repeat this process until you've found all the prime factors.
What are the prime factors of 10?
The prime factors of 10 are 2, 5
What are the prime factors of 60?
60 can be divided by 2 without leaving a remainder: 60 รท 2 = 30. Write down 2 and 30.
Now, check if the result (30) can be divided by 2 without leaving a remainder: 30 รท 2 = 15. It can, so write down 2 and 15.
The result (15) cannot be divided by 2, so move on to the next smallest prime number, 3. Check if 15 can be divided by 3 without leaving a remainder: 15 รท 3 = 5. It can, so write down 3 and 5.
The result (5) is a prime number, so we've found all the prime factors:
The prime factors of 60 are 2, 3, 5
In this topic you are asked to find the prime factors of numbers from 6 to 100.
With our Duck shoot math game you will be practicing the topic "Prime factors" from 4th grade / Multiply + Divide / Prime factors. The math in this game consists of 16 questions that ask you to identify the prime factors of numbers up to 105.
DUCK SHOOT is a fun game to learn math where you attempt to knock over all the fairground ducks in each level. In the first level there are only 6 ducks but by level 10 there are 24 fast moving "quackers quacking"...
After each level, win an additional 20 points by correctly answering a math question from your selected topic. There is no timer in this game: take as long as you like to answer the math questions correctly for a best score to get you on the DUCK SHOOT leaderboard.
