Factors and Multiples Create Chart “Factors and Multiples” Think about skip counting to 100. In skip counting, which numbers are factors and which numbers are multiples? Factor- the number you count by when you skip count Multiple- the numbers you land on (2,4,6,8,10) Where do you land if you skip count by 5 four times? Six times? How would you write these a multiplication equations? How do these equations show that 20 and 30 are multiples of 5? How can we use the word factor for some of the numbers in equations?
