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 / Multiples / LCM using product notation
To find the lowest common multiple (LCM) of two numbers, you need to find the smallest multiple that both numbers have in common. One way to do this is to use prime factorization and product notation. Here are the steps:
For example:
The prime factorization of one number is 2² x 3 x 5.
The prime factorization of the other number is 2 x 3² x 7.
The product notation is 2² x 3² x 5 x 7.
If required, you can simplify the product notation by multiplying the bases and their respective exponents. For example, 2² x 3² x 5 x 7 = 4 x 9 x 5 x 7 = 1260.
Here's an example of how to find the LCM of 12 and 15 using product notation:
Write each number as a product of prime factors.
Write the prime factors of each number in product notation, multiplying each factor by the highest power it appears in either number: 2² x 3 x 5. Note that the factor 5 appears in only one of the numbers but we still include it in the product notation.
To get the LCM as a number you can simplify the product notation by multiplying the bases and their respective exponents.
Therefore, the LCM of 12 and 15 is 2² x 3 x 5 in product notation, which is 60.
In this topic you are asked to use prime factorization to derive the lowest common multiple of 2 numbers and present your answer using product notation.
With our Choose or lose math game you will be practicing the topic "LCM 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 lowest common multiple (LCM) of 2 numbers using product notation.
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.
