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 / Fractions / Add fractions / Add fractions using LCD
Fractions with different denominators can be added by changing the fractions so that they share a common denominator.
Given the sum:
1/3 + 1/2
you do this by first finding the Lowest common multiple (LCM) of the denominators of both fractions.
The LCM is the smallest multiple shared by a set of numbers. For instance, some shared multiples of 2 and 3 are 6, 12 and 18, and the LCM is the smallest of those numbers which is 6. The LCM of 2 and 5 is 10 since 10 is the smallest multiple shared by 2 and 5.
Rewrite both fractions to use that LCM by multiplying both the numerator and the denominator by the same number. So, to convert 1/3 to have a denominator of 6, multiply both top and bottom by 2, giving 2/6.
Once you have converted both fractions so that they share the same denominator, you can add the fractions by adding the numerators.
1/3 + 1/2 = 2/6 + 3/6 = 5/6
With our Choose or lose math game you will be practicing the topic "Add fractions using LCD" from 7th grade / Number / Fractions / Fractions. The math in this game consists of 16 questions that ask you to add fractions by finding the lowest common denominator (LCD); simplify your answers where possible.
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.
