Name the Operation
Which operation should you use to solve this story problem? Why?
Simon was buying flour for his bakery. Each pound of flour costs $4. He bought 6,548 pounds of flour. What is the total cost of all the pounds of flour?
You should use multiplication because we are looking for the total cost of the pounds of flower. We know our groups, size, and the total is unknown.
What is the greater amount? Lesser amount? Times as many?
Yonce has 68 sour candies. Her grandmother has 4 times as much sour candies as Yonce. How many sour candies does Yonce have?
Greater amount = Grandmother
Lesser amount = Yonce
Times as many = 4 times as much
What is the digit of focus in this problem?
The value of the 5 in 785,347 is 1,000 times greater than the value of the 5 in which number?
The digit of focus is 5
What is one big idea we can use for multiplicative comparison?
1. First subject listed in the comparison statement is the greater amount.
2. If we are looking for the greater amount, we should multiply.
3. If we are looking for the lesser amount, we should divide.
Which operation should be used to solve the story problem? Why?
If a total of 2,052 Jolly Ranchers are split into 6 equally sized jars, how many Jolly Ranchers are in each jar?
You should use division because we know the total is 2,052. We know there are 6 groups, and we are looking for the size of each group.
What is the greater amount? Lesser amount? Times as many?
Makhai and Joshua were playing a basketball game. Joshua took 36 free throws. He took 4 times the amount of free throws that Makhai took. How many free throws did Makhai take?
Greater amount: Joshua
Lesser amount: Makhai
Times as many: 4 times as many
How many loops should you make for this problem? Why?
The value of the 5 in 785,347 is 1,000 times greater than the value of the 5 in which number?
You should make 3 loops because 1,000 times greater is 3 place values away.
What is one big idea we can use for equal groups and thinking about the operation to solve?
If you are looking for the total, you should divide.
If you have the total amount, you should divide.
Which operation should be used to solve the story problem? Why?
Shaniyaah has 104 hair ties. That is 4 times as many hair ties as Aamirah. How many hair ties does Aamirah have?
We should use division because we are looking for Aamirah's hair ties. In the comparison statement, "that" is the first subject and it refers to shaniyaah's hair ties. Shaniyaah is the greater amount and is known, but Aamirah is the lesser amount and unknown. When we are finding the lesser amount we should divide.
What is the greater amount? Lesser amount? Times as many?
Ms. Foster counted 56 pairs. She has 3 times as many pairs of shoes as Ms. Newnam. How many pairs of shoes does Ms. Sankar have?
Greater amount: Ms. Foster
Lesser amount: Ms. Newnam
Times as many: 3 times as many
How many loops? What should they be labeled? Which direction should you move?
The digit 2 in 20,439 is 1,000 times greater than the value of the 2 in which of the following numbers?
Loops: 3 loops
Label: divided by 10
Direction: To the right because we are looking for a lesser place value
What is one big idea we can use for comparing place value?
1. If we are looking for the greater amount, we should loop and label to the left.
2. If we are looking for the lesser amount, we should loop and label to the right.
What operations would you use to solve this story problem?
Mohammad is buying video games for Christmas. He wants 3 new PS4 games and 2 controllers. The cost of each is listed below.
What is the total amount of money Mohammed will spend?
We would use multiplication to find the cost of the ps4 games and the cost of the controllers. Then we would add up the total costs
What is the greater amount? Lesser amount? Times as many?
Mr. Frazier has 32 ties. That is 4 times as many times as Mr. Miller. How many ties does Mr. Miller have?
Greater amount: Mr. Frazier (that)
Lesser amount: Mr. Miller
Times as many: 4 times as many
How many loops? What should they be labeled? Which direction should you move?
The digit 2 in 20,439 is 1,000 times greater than the value of the 2 in which of the following numbers?
Loops: 3 loops
Label: divided by 10
Direction: To the right because we are looking for a lesser place value
What is one big idea we can use for unknown boxes?
1. Reread the story problem line by line to figure out what is unknown.
2. List the unknowns in sequential order.
3. Make sure the final unknown matches the final task
What operations should you use to solve this story problem?
Ms. Bryant is buying school uniform shirts and shoes for the scholars at LPBV. She buys 30 uniform shirts and 30 uniform shoes. Each uniform shirt costs $6. Uniform shoes cost twice as much as uniform shirts. What is the difference, in dollars, between the uniform shirts and shoes?
We should multiply 30 uniform shirts by 6 and 30 uniform shoes by 6 to get the costs. Then we should subtract to find the difference.
What is the greater amount? Lesser amount? Times as many?
Kristina drove 18 miles in April. That was twice as many miles as she drove in March. How many miles did Kristina drive in March?
Greater amount: April
Lesser amount: March
Times as many: 2 times as many
How many loops? What should they be labeled? Which direction should you move? What place value should you end in?
In which of the following numbers is the digit 5, 1,000 times greater than the value of the digit 5 in the number 2,456?
Loops: 3 loops
Label: x 10
Direction: To the left because we are looking for a greater place value
End in the ten thousands place
What is one big idea we can use for multi-step story problems?
1. The unknown in one step becomes a known in a later step.
2. Multi-step means more than one step
