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
5th grade / Multiply + Divide / Factors / Prime factors
Factors are numbers that divide into a number without a remainder. The factors of 12 are 1, 2, 3, 4, 6 and 12. Prime factors are the factors of a number that are prime numbers (numbers that can only be divided evenly by 1 and themselves).
To find the prime factors of a number, first list all of it's factors, then decide which of them are prime. Express the number as a product of it's prime factors.
So, in the first question from the lesson we have the number 6. The factors of 6 are 1, 2, 3 and 6, and the prime factors are 2 and 3 (1 is not considered a prime number).
Starting with the smallest prime factor, divide the original number by that value, and continue to do so until the result is no longer divisible by that prime factor without a remainder. Move to the next largest prime factor and continue until you have the original number expressed as a product of it's prime factors.
Prime factors of 6: 2 x 3
Prime factors of 20: 2 x 2 x 5
Prime factors of 48: 2 x 2 x 2 x 2 x 3
Prime factors of 21: 3 x 7
With our Mix and match math game you will be practicing the topic "Prime factors" from 5th grade / Multiply + Divide / Factors. The math in this game consists of 16 questions that ask you to identify the prime factors of each number up to 99.
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?
