Game: ROCK FALL
Aim: Smash all the falling rocks
Method:
Click / tap on each falling rock. Answer the question in the box as quickly as you can.
There are only 4 questions in this game so it is quite short... if you can get those rocks!
Your final score is based on number of questions answered right / wrong, and the time taken.
5th grade / Multiply + Divide / Factors / Prime factors
Factors are numbers that divide into a number without a remainder. The factors of 12 are 1, 2, 3, 4, 6 and 12. Prime factors are the factors of a number that are prime numbers (numbers that can only be divided evenly by 1 and themselves).
To find the prime factors of a number, first list all of it's factors, then decide which of them are prime. Express the number as a product of it's prime factors.
So, in the first question from the lesson we have the number 6. The factors of 6 are 1, 2, 3 and 6, and the prime factors are 2 and 3 (1 is not considered a prime number).
Starting with the smallest prime factor, divide the original number by that value, and continue to do so until the result is no longer divisible by that prime factor without a remainder. Move to the next largest prime factor and continue until you have the original number expressed as a product of it's prime factors.
Prime factors of 6: 2 x 3
Prime factors of 20: 2 x 2 x 5
Prime factors of 48: 2 x 2 x 2 x 2 x 3
Prime factors of 21: 3 x 7
With our Rock fall math game you will be practicing the topic "Prime factors" from 5th grade / Multiply + Divide / Factors. The math in this game consists of 16 questions that ask you to identify the prime factors of each number up to 99.
ROCK FALL is based on the road traffic warning sign for falling rocks - a sign that seems a bit less useful than somebody getting up there on that cliff and actually doing something about it... Anyway, the rocks are falling and it is your job to stop them hitting the road below, or at least stopping them hitting the road below too many times and breaking it. Smash the rocks by clicking or tapping on them (not so easy in real life of course) - they will turn into snowflakes and float gently down into nothing.
There are 4 rocks to stop and not much time to do it (if you want to get a good score and get on the leaderboard). This game is fun and fast and requires good reflexes and a good strategy. Plan to break the smaller rocks first if you want a good score because the rocks fall faster as the game progresses. It also helps to decide where on their path you plan to click / tap the rocks.
