When working with division, it’s important to say “groups of” – for example: 50/10=5 Say “50 is composed of 5 groups of 10” or ask the question “how many groups of 10 are in 50”?
The following array, consisting of four columns and three rows, could be used to represent the number sentence 3 x 4 = 12, 4 x 3 =12, 3 + 3 + 3 + 3 = 12 and 4 + 4 + 4 =12
Area Model of Division - I will admit, this is another new concept for me! Below are two teachers explaining the concept.

Videos and tasks for your standards! The
videos can be used in various ways, I see power in viewing them prior to
teaching the concept. They do a nice job of explaining the concept in easy
words (for the kids) to understand.
