Factors and Mulitples

Students took the chapter 2 test in math today.  I discovered that many students are mixing up multiples and factors.  

Multiples are products of a number.  The multiples of 2 are 2, 4, 6, 8, 10, …

Factors are the numbers that can be multiplied to get a certain numbers.  For example, the factors of 10 are 1 (1 x 10=10), 2 (2 x 5=10), 5 (5 x 2=10), and 10 (10×1=10).  Factors are always less than or equal to the number you’re working with.

To practice factors, check out this site:

Because of the misunderstanding, we are going to spend some time next week reviewing multiples and factors and retest those skills next week.  We will consider this morning’s test a practice exam and I will take the scores on next week’s re-test instead.
