A T-shirt cost $9 at mall. A pair of shoes costs 5 times as much s a T-shirt. How much does a pair of shoes cost?

• The first thing I would do is add 9 + 5

• The first thing I would do is subtract 9 - 5

• The first thing I would do is multiply 9 x 5

• The first thing I would do is divide 9 / 5

A T-shirt cost $9 at mall. A pair of shoes costs 5 times as much s a T-shirt. How much does a pair of shoes cost?

• Then I would draw a 5 x 9 array. Write a sentence The shoes cost $45 dollars. Finally, I would explain how I solved the problem. I would write, " I solved this problem by realizing that if the shoes cost 5 times more I would multiply 9 x 5

• I would simply write 9 x 5

• I solved this problem by realizing that if the shoes cost 5 times more I would multiply 9 x 5.

There are 40 chairs in the gym. Mr. Brown wants to set them up in rows of 8. How many rows can he make?

• I take 40 and then add 8 and I know there are 48 chairs total.

• First I line up each chair in the gym, then I count them by rows and try to figure out the answer.

• I start with eight and put them in rows of four

• If there are 40 chairs in 8 rows, I draw 40 dots in eight rows, circle each row and I would have 5 columns. Then I would know 40 divided by 8 equals five.

Jon has 8 pieces of string. Each piece of string is 5 feet long. How many feet of string does Jon have in all?

• I would draw 5 pieces of string Label them 8 ft. Write - The string is 35 feet feet long because 8 x 5 = 35 ft

• 1. I would draw 8 pieces of string
  2. Label them 5 ft.
  3. Multiply 5 x 8
  4. Write - The string is 40 feet feet long because 8 x 5 = 40 ft
• I would add 8 + 5

• I would add 8 + 5 = 13 feet

Maddie picked 45 plums and divided them evenly into 5 bags for her friends. How many plums did she put in each bag?

• I would draw four circles, make marks in each until I reached 40. Count the marks in one circle and then I would know 10 plums fit in each bag. I would write 40 divided by 5 equals 9.

• I would draw 45 plums and circle them evenly

• I think there are 6 plums in the bag.

• I would draw five circles, make marks in each until I reached 45. Count the marks in one circle and then I would know 9 plums fit in each bag. I would write 45 divided by 5 equals 9.

Fill in the answer to the equations. Then write a story problem to match the problem 9 × 4 = ____

• write the fact family

  pick a person with a problem

  write the story

  
  

  Sally had bought a pair of red sneakers for $9. She knew the top that matched cost 4 times as much. How much did the top cost?

  
  

  The top cost $36.00

• Just write 36 that's the answer

14 ÷ 2 = ____ My Story Problem: Remember

State how many there are in all for a division problem

Share in equal groups

Ask the question to find out how many are in each group. I would write a question like this:

• There were 14 cookies on the tray Justin wanted to share them with Oscar. How many cookies did each boy get?

  
  

  Each boy got 7 cookies because 14 divided by 2 equals 7

• There were 2 cookies on the tray Angel wanted to share them with Axel, Brandon and Dilan. How many cookies did each boy get?

  
  

  Each boy got 4 cookies because there are 4 boys

• Two times 7 equals fourteen so I would just write this.

Write a fact family for this array

• 5 x 2 = 10 . 2 x 5 = 10 . 10 -5 = 5 . 10 - 2 = 8

• There were 14 cookies on the tray Justin wanted to share them with Oscar. How many cookies did each boy get?

  
  

  Each boy got 7 cookies because 14 divided by 2 equals 7

The Game Store just got 60 new video games. Devon is putting the games into stacks of 10. How many stacks can he make if he uses all 60 games?

• Devon can make 6 stacks of twelve games each.

• Devon should just put them all in a box

• Devon can make 6 stacks of 10 games because 6 x 10 equals 60.

• Devon can make two stacks of 15

The Game Store has 7 stacks of board games for little kids. If there are 5 board games in each stack, how many board games is that in all?

• The game store has 35 boards games because seven times five is thirty five. 7 x 5 = 35

• The game store has 12 games because 7 + 5 = 12

• The game store store has 7 + 7 +7 = 21 games
