Game: MIX AND MATCH
Aim: Drag question blocks to answer boxes
Method:
Drag the question block over the right answer box to tidy up the play room. Points are added and taken away automatically.
Click the answer boxes to hear the answer for each box. You must answer 5 questions correctly to complete the game
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 Mix and match 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.
In this game we are in a room with lots of toys - and the room needs clearing up - you need to put the play blocks back in the right boxes to tidy the room and win the game...but which is the right box for each block? Well, you can work that out by comparing the question on the block with the math answer on each of the boxes - you should drag the question block into the box whose math answer matches the picture question.
You can listen to the spoken math answer by clicking on the individual boxes. There are 5 blocks to clear up - but if you put them in the wrong boxes, there will be more... Anyway, tidy is good and practicing math is better so start now and see how you get on...
This game reinforces the math you learned or revised in the lesson by asking you to match each question to the correct answer. If you are older you may not like the childish reference to toys, but don't worry - there are other games to play, and who knows - you might like a trip down memory lane?
