Winner Corona App of the Week!
Factor samurai is a great way to learn times tables. You play as the samurai whose sacred duty is to cut all the numbers down to their prime factors.
You will be thrown one number after the next, cut them up if they can be factored into smaller values, if not, if they are prime, do not cut them.
Prime numbers are numbers that cannot be divided into small whole numbers. Two, three, five, seven, eleven, and thirteen are all examples of prime numbers. Four is not prime because it can be broken down in the whole numbers two times two.
Factor Samurai will reinforce the arithmetic principles of multiplication and division by continually challenging the player to remember which numbers can be factored into smaller values, and which ones can't.
As the player slices numbers into factors, those factors can be broken down further, until they are split into their prime factors.
Knowing that 63 is 3 times 3 times 7 or that 128 is 2 raised to the seventh power (7 twos!) is how you become a true Factor Samurai!
Factor Samurai is used extensively in the classroom. More than half of the recorded downloads are to public schools.

1 change for 5 stars
This app is amazing. So many apps are just flash cards with a theme but this is different. Kids also get familiar with recognizing prime numbers quickly and just how composite some numbers are.
I REALLY wish I could increase the size of the numbers to 100 and beyond though. I would pay to upgrade even!
Fantastically Fun and Deceptively Educational
This app has Samurais in it which makes it intrinsically sweet and worth 5 stars by itself, but once my child tried it, that's when the magic happened. It’s addicting and fun to play, and feels more like a video game than a math lesson. The artwork is also appealing, the music adds to the intensity with incredibly satisfying swiping sounds (ah the splat of a divisible number), and I liked being able to get new swords and faster number tosses as we progressed in the game. A great way for children to learn, or for an adult to dust up on, some fundamental math skills. Thank you, Factor Samurai, my child and I are now Times Table geniuses!
Great way to have fun learning math
I experienced a couple glitches, but love the game otherwise.
