Q. What is a break apart strategy?
Breaking apart an addend is a mental math strategy for addition. This strategy involves breaking up one addend in an equation into more manageable parts. Like many other mental math strategies, this strategy encourages students to think flexibly and to manipulate numbers in different ways.
Q. Why would you break apart an array?
Breaking apart arrays is another effective strategy for students who are learning multiplication, and helps model distributive property. It’s also important that students know they can break apart a multiplication problem (an array) in order to make the problem simpler to solve.

Q. Why do you need to break arrays for multiplication?
In this inquiry-based activity for grades 1-4, students will apply distributive property to decompose units. Breaking apart arrays is another effective strategy for students who are learning multiplication, and helps model distributive property.
Q. Which is the easiest way to subtract a number?
Breaking apart/ separating – subtract one number in parts from the other number which stays intact, always starting with largest place value to subtract a. 54 – 23 = 23 can be broken into 20 + 3 54 – 20 = 34 34 – 3 = 31 or 56 – 29 = 29 can be broken into 20 + 6 + 3, breaking 9 into 6 + 3 makes it easier to subtract 56 – 20 = 36
