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.
7th grade / Number / Multiples Factors Primes / Factors / HCF using product notation
The highest common factor (HCF) of two numbers is the largest factor that is common to both numbers. It is also known as the Greatest Common Factor (GCF).
Product notation is a way of representing a number as a product of its prime factors. For example, the prime factorization of 24 can be written as 2³ × 3¹. To find the HCF of two or more numbers using product notation, you need to follow these steps:
Example 1: Find the HCF of 18 and 24.
The prime factorization of 18 is:18 = 2¹ x 3²
The prime factorization of 24 is:24 = 2³ x 3¹
To find the HCF of 18 and 24, we take the lowest power of each prime factor that appears in both factorizations:
HCF(18,24) = 2¹ × 3¹ = 6
Example 2: Find the HCF of 16 and 28.
The prime factorization of 16 is:16 = 2⁴
The prime factorization of 28 is:28 = 2² x 7¹
To find the HCF of 16 and 28, we take the lower power of each prime factor that appears in both factorizations:
HCF(16,28) = 2² = 4
In this topic you are asked to find the highest common factor of pairs of numbers presenting your answers in product notation.
With our Rock fall math game you will be practicing the topic "HCF using product notation" from 7th grade / Number / Multiples Factors Primes / Multiples Factors Primes. The math in this game consists of 16 questions that ask you to identify the Highest Common Factor (HCF) using product notation for the given pairs of numbers.
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.
