How can you use the math fact 5 x 8 = 40 to help you solve 6 x 8 ?
If 5 x 8 equals 40 then we need to add another 1 x 8 to get to 6 x 8. So 5 x 8 = 40 plus 1 x 8 = 8 equals 40 + 8. Therefore 6 x 8 = 48.

Each car on a Ferris wheel can hold 4 people.
There are 34 people in line.
How many cars are needed for everyone to get on?
34 divided by 4 = 8 cars with 2 people left over. Therefore we need 9 cars for everyone to get on.

Multiply 752 x 8 using expanded form (multiplication breakdown)
752 = 700 + 50 + 2
752 x 2 is the same as 700 x 2 plus 50 x 2 plus 2 x 2
700 x 2 = 1400 plus 50 x 2 = 100 plus 2 x 2 = 4
1400 + 50 + 2 = 1452

Which multiplication fact will help you find the answer to 65 divided by 9?
If I look at the multiples of 9 I see that 9 x 7 = 63. So I know that 65 divided by 9 = 7 with a remainder of 2.

Bottles are packaged 7 to a carton.
How many cartons are needed for 79 bottles?
79 divided by 7 = 11 cartons with 2 bottles left over.
Therefore, we need 12 cartons for 79 bottles.

Estimate the product of 787 x 32.
To estimate we round 787 to 800 and 32 to 30
800 x 30 = 8 x 3 plus three zeroes = 24 000
Our estimate is 24 000

A ruby-throated hummingbird flaps its wings about 60 times each second.
How many times would it flap its wings in 1 minute?
There are 60 seconds in a minute so we need multiply the 60 flaps per second by 60 seconds.
60 x 60 = 3600

How can you use the products of 16 x 100 to find the product 16 x 99?
16 x 100 is equal to 1600 so I know that 16 x 99 is just 16 less that 1600 so:
16 x 99 = 1600 - 16 = 1584

Estimate the quotient of the following division problem:
2136 divided by 72
To estimate we round: 2136 to 2100 and 72 to 70
2100 divided by 70 is similar to 210 / 7
Take off the zero 21 / 7 = 3 so 210 / 7 = 30
so 2136 divided by 72 is approximately 30

A plant can produce 9 strawberries.
These are packed 27 strawberries to a basket.
How many plants will it take to produce 30 baskets of strawberries?
To find out how many strawberries we need to produce we multiply 30 baskets by the 27 strawberries needed to fill each basket: 30 x 27 = 810 strawberries are needed to fill 30 baskets.
To find out how many plants it will take to produce 810 strawberries we need to divide 810 by 9
810 / 9 = 90. Therefore we need 90 plants.

Explain in your own words how the Partial Quotient Strategy got its name? (in other words: Why is it called the Partial Quotient Strategy?)
As we work though the partial quotient algorithm we are finding parts (partial) of the answer (quotient).
