Go Math Grade K Chapter 5 Answer Key Addition-7
Number pair for 5 are (3, 2), (4, 1) and (5, 0),

Explanation:
To show a number pair for 5 we take numbers as x and y, So, x + y = 5 and we will take numbers below 5 only, as if x = 3 then y = 5 – x = 5 -3 = 2, now if x = 4 then y = 5 – 4 = 1, now if x = 5 then y = 5 – 0 = 5,
So number pair for 5 is (3, 2), (4, 1) and (5, 0).

Lesson 5.6 Algebra • Write Addition Sentences

Essential Question How can you solve addition word problems and complete the addition sentence?
To solve addition word problems the main components of addition word problems include:
a. The Relationship of the Numbers – Know the problem type and help to solve for the action in the problem,
b. Differentiate the Numbers – Take just the right numbers so that it can read the problem without getting bogged down with the computation,
c. Use Academic Vocabulary – And be consistent in what we are using,
d. Stop Searching for the “Answer” – it’s not about the answer; it’s about the process,
e. Differentiate between the Models and the Strategies – one has to do with the relationship between the numbers and the other has to “solve” or compute the problem.

Addition sentence is a number sentence used or simply an equation used to express addition.
For example:

I have 2 cars, I purchased 3 more, how many cars do I have now in all?
The addition sentence is 2 + 3 = 5,
