Factors and Multiples of Numbers

Review of 4th grade math: I can find the factors of a number under 101.

1. Vector Kids– divisibility rules for 4-digit numbers- challenging!
2. Catch a STAR-multiples game that requires a solid times tables knowledge.
3. Factors of 10 Ball Shoot-  Shoot the ball # to another ball # so the product is 10
5. Sliding Tile Factorization Game  Slide a number over another to capture it, if it is a factor of the other. Number 1 is only supposed to be used to capture a prime number.
6. Octopus Factors  Move counters up the legs of an octopus but only when the number on the circle is a multiple of the number on the card.
7. Not a Factor Choose a number that is NOT a factor of the given number.
8. Product Four in a Row-NCTM Illuminations site
