math word problems!

Word Problem Mania!

HOW do we complete a word problem?

Think about CBS… but this time we’re not watching TV! We are solving word problems!

C: Circle the important numbers.

B: Box in the question.

S: Solve & label the word problem!

Let’s try an example together!

Tyler finds 38 golf balls around his house. He also finds 46 golf balls along the golf course. (Did you know that Tyler is SUCH a great golfer?) How many golf balls does Tyler find in all?

Great work!

Look at #1 on your paper. You

are going to solve

this one on your own now!

I will pull up the screen and do this problem with you after everyone has

tried it!

C: Circle the important numbers.

B: Box in the question.

S: Solve & label the word problem!

This time there will be MORE than one step in

the word problem! You will have to take your time and think

really hard to solve these tricky math word

problems!

This time, when we don’t know part of

the word problem we will represent what

we don’t know with a letter!

This is called ALGEBRA!

(You are SO grown up to be doing algebra already. Your teachers didn’t learn

algebra until they were in middle school!)

Here is an example:

42 + 13 – 3 = x

or

62 + 37 – 41 = a

Let’s try an example together!

Kendyl had 56 balloons. She blew up 76 more balloons.

Then 17 popped. How many balloons is Kendyl left with?

(These problems have more than one step… we might have to add AND

subtract in some of them! Yikes!)

C: Circle the important numbers.

Then 17 popped. How many balloons is Kendyl left with?

B: Box in the question.

Kendyl had 56 balloons. She blew up 76 more balloons.

Then 17 popped. How many balloons is Kendyl left with?

S: Solve & label the word problem.

Kendyl had 56 balloons. She blew up 76 more balloons.

Then 17 popped. How many balloons is Kendyl left with?

Remember that we need to use a letter to represent the information that we don’t know yet!

56 + 76 – 17 = bNumber model:

S: Solve & label the word problem.

Kendyl had 56 balloons. She blew up 76 more balloons.

Then 17 popped. How many balloons is Kendyl left with?

Now we can solve for the letter b!

56 + 76 – 17 = bNumber model:

Answer: 56 + 76 – 17 = 115 balloons

Fabulous!

How about we do one more as a
