Factors and Multiples of Numbers
Review of 4th grade math: I can find the factors of a number under 101.
- Vector Kids– divisibility rules for 4-digit numbers- challenging!
- FACTOR FEEDER- similar to PacMan. Eat the Factors
- Factors of 10 Ball Shoot- Shoot the ball # to another ball # so the product is 10
- Arrays and factors Drag rectangles to show the factorizations of a given number.
- 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.
- 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.
- Not a Factor Choose a number that is NOT a factor of the given number.
- Factor Finder: NCTM Illuminations site. Pick a Number, then draw AND write the facts.
