Game: UXO
Aim: Knock out the targets, avoid the bombs
Method:
Click or tap and hold to destroy the objects while avoiding the bombs. When you knock out all 10 targets, you must answer the question to continue to the next level. There is a time limit of 30 seconds to get all 10 targets or you lose 50 points.
Scoring is :
Hit target : +10
Hit bomb : -5
Right answer : +50
Wrong answers : -20
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 UXO 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.
UXO is a fun game to learn math where you attempt to knock over all the target objects while avoiding clicking / tapping on the bombs.
After each level, win an additional 50 points by correctly answering a math question from your selected topic. Wrong answers lose you 20 points but you can answer multiple times. Each level lasts 30 seconds: if you haven't cleared all the targets in that time, you lose 50 points. High scores can be added to the UXO leaderboards.
