Factor pairs

The topic  is a topic under the 6th Grade Math Mission. This exercise introduces the idea of factor pairs for composite numbers.

Types of Problems
There are two types of problems in this exercise:


 * 1) Identify pairs of factors of the number: This problem provides a number or area that is an integer. The student is asked to identify all the options from a multiple select list that are factor pairs for the number, or possible lengths and widths for the rectangleFp1-too.png
 * 2) Find the other pair in the factor pair: This problem provides a situation where one half of a factor pair is provided. The student is expected to fill in the other half of the factor pair as appropriate.Fp2-too.png

Strategies
Being able to create a factor tree quickly can help to perform this problem well. Factor trees are also valuable for concepts like LCM and GCF which lead into increased ability with fractions.
 * 1) The area of a rectangle is a product so it is a natural word problem to identify factor pairs.
 * 2) The Find the other pair in the factor pair problem is sometimes worded as a split into rows or columns word problem.
 * 3) Given one factor, division of the large number by one factor will yield the other.
