21. “Word Problems?

22. Step 1
GIVEN (Identify the given)
Let us READ and UNDERSTAND the problem.
What are you trying to figure out?
Here’s an example:

23. Yesterday, Alex saw 14
birds in his backyard.
Today, he saw 12. How
many birds did he see in
all?
In this problem, what are
you trying to figure out?

24. Given:
14 birds in his backyard
Yesterday
12 birds in his backyard
Today

25. Step 2
OPERATION
(Operation to be use)
Get a PLAN.
How will you answer the question?
Should you ADD or
SUBTRACT?

26. Look for clues.
Here are some CLUE WORDS
that will help you decide
what to do.

27. Let’s look at the
example again.
Yesterday, Alex saw 14 birds in his backyard.
Today, he saw 12. How many birds did he
see in all?
Do you see any CLUEWORDS?

30. Step 3
Solve the problem
SOLVE it!
Write a number sentence using the
information in the problem, and…

31. If you wrote…
14 + 12 = 26 then…
You’re right!

32. Step 4
Check your work.
LOOK BACK.
Does your answer fit the question?

33. We had to find out how many birds Alex saw in
all.
We added the number he saw yesterday and
the number he saw today.

34. Our answer was “Alex saw 26 birds in
all.”
It makes sense!

35. Here are the
steps once more:
