Game: CHOOSE OR LOSE
Aim: Choose the right answer; beat the clock
Method:
You start the game with 50 points. Each question has 2 to 4 answers. Select the correct answer before your time runs out to score points. Right answers are +10, wrong answers are -2, out of time is -5.
This is a timed game. Your final score is equal to the total score minus 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 2ยณ ร 3ยน. 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 = 2ยน x 3ยฒ
The prime factorization of 24 is:24 = 2ยณ x 3ยน
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) = 2ยน ร 3ยน = 6
Example 2: Find the HCF of 16 and 28.
The prime factorization of 16 is:16 = 2โด
The prime factorization of 28 is:28 = 2ยฒ x 7ยน
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) = 2ยฒ = 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 Choose or lose 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.
Our CHOOSE OR LOSE game is a simple activity to help secondary math learners and will improve the speed at which you can solve problems in the given topic. It does not rely on the learner typing in the answer. Rather, the learner must choose the correct answer from a list of 2, 3 or 4 similar answers.
CHOOSE OR LOSE encourages faster problem-solving for common and vital secondary math topics. CHOOSE OR LOSE is a timed game with a leaderboard for each topic at each of the 4 levels on offer. You can play the game with or without audio and robots.
UXO * Duck shoot * The frog flies * Pong * Cat and mouse * The beetle and the bee
