math gnumch-factors

 Manuel Tondeur & Timothee Giet

Description: Guide the Number Muncher to all the factors of the number at the top of the screen.

Goal: Learn about multiples and factors.

Manual: The factors of a number are all the numbers that divide that number evenly. For example, the factors of 6 are 1, 2, 3 and 6. 4 is not a factor of 6 because 6 cannot be divided into 4 equal pieces. If one number is a multiple of a second number, then the second number is a factor of the first number. You can think of multiples as families, and factors are the people in those families. So 1, 2, 3 and 6 all fit into the 6 family, but 4 belongs to another family.

Gnumch Multiples
screenshot gnumch-multiples icon gnumch-multiples difficulty level 3

math gnumch-multiples

 Manuel Tondeur & Timothee Giet

Description: Guide the Number Muncher to all the multiples of the number at the top of the screen.

Goal: Learn about multiples and factors.

Manual: The multiples of a number are all the numbers that are equal to the original number times another number. For example, 24, 36, 48 and 60 are all multiples of 12. 25 is not a multiple of 12 because there isn't any number that can be multiplied by 12 to get 25. If one number is a factor of a second number, then the second number is a multiple of the first number. Again, you can think of multiples as families, and factors are the people who belong to those families. The factor 5, has parents 10, grandparents 15, great-grandparents 20, great-great-grandparents 25, and every extra step of 5 is another great- in front! But the number 5 does not belong in the 8 or 23 families. You can't fit any number of 5s into 8 or 23 with nothing left over. So 8 isn't a multiple of 5, nor is 23. Only 5, 10, 15, 20, 25 ... are multiples (or families or steps) of 5.

Gnumch Primes
screenshot gnumch-primes icon gnumch-primes difficulty level 6

math gnumch-primes

 Manuel Tondeur & Timothee Giet

Description: Guide the Number Muncher to all the prime numbers.

Goal: Learn about prime numbers.

Manual: Prime numbers are numbers that are only divisible by themselves and 1. For example, 3 is a prime number, but 4 isn't (because 4 is divisible by 2). You can think of prime numbers as very small families: they only ever have two people in them! Only themselves and 1. You can't fit any other numbers into them with nothing left over. 5 is one of these lonely numbers (only 5 × 1 = 5), but you can see that 6 has 2 and 3 in its family as well (6 × 1 = 6, 2 ×3 = 6). So 6 is not a prime number.
