### Word Problem Mania!

### AMAZING WORK! your pencil down after you have solved it so I know you are ready!

Third Grade fun with math word problems!

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?

C: Circle the important numbers.

S: Solve & label the word problem.

38 + 46 = 84 golf balls

Great work! How about we do one more as a class?

Here we go…

- The Bridge family takes 9 tents when they go camping. The Bartlett family takes 7 tents, and the McHugh family takes 5 tents. How many tents do they take in all?

C: Circle the important numbers.

B: Box in the question.

- The Bridge family takes 9 tents when they go camping. The Bartlett family takes 7 tents, and the McHugh family takes 5 tents. How many tents do they take in all?

S: Solve & label the word problem.

9 + 7 + 5 = 21 tents

answer

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!

Alyssa jumped 11 times. Nora jumped 15 times. How many times did they jump altogether?

Way to go! everyone has tried it! Now try #2!

We will check it together after everyone is finished. Set your pencil down after you have solved it so I know you are ready!

Riley kicked a soccer ball 102 times. Xariyan kicked a soccer ball 94 times. How many more times did Riley kick the soccer ball than Xariyan?

Here is our answer! your pencil down after you have solved it so I know you are ready!

Number model:

102 - 94 = 8

Answer:

8 more times

Woohoo! your pencil down after you have solved it so I know you are ready! Now try #3!

We will check it together after everyone is finished. Set your pencil down after you have solved it so I know you are ready!

Bianca had 25 pencils. Emily had 75 pencils. What is the total number of pencils that they had?

Here is our answer! your pencil down after you have solved it so I know you are ready!

Number model:

25 + 75 = 100

Answer:

100 pencils

Let’s do one more! your pencil down after you have solved it so I know you are ready! Try #4!

We will check it together after everyone is finished. Set your pencil down after you have solved it so I know you are ready!

Konnor and Elijah read 10 more books than Luke. Luke read 49 books. How many books did Konnor and Elijah read?

Here is our answer! your pencil down after you have solved it so I know you are ready!

Number model:

49 + 10 = 59

Answer:

59 books

Amazing job! your pencil down after you have solved it so I know you are ready! Now are you ready for a REAL challenge?

Let’s review our CBS rules: your pencil down after you have solved it so I know you are ready!

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: will represent what we don’t know with a letter!

42 + 13 – 3 = x

or

62 + 37 – 41 = a

Let’s try an example together! will represent what we don’t know with a letter!

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 will represent what we don’t know with a letter! : Circle the important numbers.

Kendyl had 56 balloons. She blew up 76 more balloons. Then 17 popped. How many balloons is Kendyl left with?

B will represent what we don’t know with a letter! : 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 will represent what we don’t know with a letter! : 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 = b

Number model:

S will represent what we don’t know with a letter! : 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 = b

Number model:

56 + 76 – 17 = 115 balloons

Answer:

Fabulous! will represent what we don’t know with a letter! How about we do one more as a class?

Here we go! will represent what we don’t know with a letter!

Evan has a large collection of books. He gave his best friend 14 books and his brother 7 books. Now Evan has 60 books. How many books did he start with?

C will represent what we don’t know with a letter! : Circle the important numbers.

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

60 + 7 + 14 = n

Answer:

Great work! will represent what we don’t know with a letter! 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!

Ronan had 10 Snickers bars. Michael gave him some Hershey bars and 20 Crunch bars. Ronan now has 42 candy bars total. How many Hershey bars did Michael give Ronan?

Way to go! everyone has tried it! Now try #2!

Answer:

20 shirts

Let’s do one more! your pencil down after you have solved it so I know you are ready! Try #4!

We will check it together after everyone is finished. Set your pencil down after you have solved it so I know you are ready!

Mrs. McHugh bought 3 hot dogs. Mrs. Bartlett bought 400 more. Then Mr. Bridge ate some of them. They only had 303 left. How many hot dogs did Mr. Bridge eat?

Here is our answer! your pencil down after you have solved it so I know you are ready!

Number model:

3 + 400 – h = 303

Answer:
