UEQ.: Why is it important to know the factors of numbers?Ans.: I think it is important to know the factors of numbers so that I can solve math problems that involve multiplication and division.Concept #1 – Arrays and Factor PairsLEQ: How do I use arrays to represent factor pairs?Ans.: The first factor in a number model represents the number of rows. The second factor represents the amount of columns. The total number of dots equal the product.

Concept # 2 – Prime and CompositeLEQ: How do I use divisibility rules to determine prime or composite numbers?Ans.: A prime number has only two factors (1 and itself). I use divisibility rules to see how many factors a number has. e second factor represents the amount of columns. The total number of dots equal the product.

Concept #3 – Square Numbers & Square RootLEQ: What is the difference between square

numbers and square roots?Ans.: A square number is a number times itself.

(product) A square root is a number that has 2 equal factors.

Concept #4 – Factor StringLEQ: How do I find prime factorization using

factor trees?Ans.: I find prime factorization using factor trees

by finding factor pairs. I divide the product until ONLY PRIME numbers are left.
