Flipped Math 0.2 Part 3

What's the initial value? And why?

So far we have

97

for our equation.

Are we going to be adding or subtracting?

Which word or words in the story told us that we are going to be subtracting?

So now we have

97 -

for our equation.

How much are we subtracting?

So now we have

97 - 10u

for our equation.

What is missing?

So our equation is

m = 97 - 10u

We must define our variables.

What does the m represent?

So our equation is

m = 97 - 10u

m = money on the card

What does the u represent?

Now we are set up for success!

a.) m = 97 - 10u

b.) m = money on the card

u = number of times he uses the card

To answer part c we have to know where in our equation we should put the 6.

This is what we have so far to solve part c.

m = 97 - 10u

m = 97 - 10(6)

Do we have to solve an equation like in 0.1 or can we simplify by using the order of operations or a calculator.

This is what we have so far to solve part c.

m = 97 - 6u

m = 97 - 6(6)

What is the unit of measure for the answer to part c?

Now we are set up for success!

m = 97 - 10u

m = money on the card

u = number of times he uses the card

To answer part d we have to know where in our equation we should put the 77.

This is what we have so far to solve part d.

m = 97 - 10u

77 = 97 - 10u

Do we have to solve an equation like in 0.1 or can we simplify by using the order of operations or a calculator.

This is what we have so far to solve part d.

m = 97 - 10u

77 = 97 - 10u

What should we do first to both sides of the equation as we try to isolate the u?

This is what we have so far to solve part d.

m = 97 - 10u

77 = 97 - 10u

-20 = -10u

What should we do next to both sides of the equation as we try to isolate the u?

This is what we have so far to solve part d.

m = 97 - 10u

77 = 97 - 10u

-20 = -10u

2 = u

What is the unit of measure for the answer to part d?

What's the initial value? And why?

So far we have

4

for our equation.

Are we going to be adding or subtracting?

Which word or words in the story told us that we are going to be adding?

So now we have

4 +

for our equation.

How much are we adding?

So now we have

4 + 11h

for our equation.

What is missing?

So our equation is

c = 4 + 11h

We must define our variables.

What does the c represent?

So our equation is

c = 4 + 11h

c = charge for babysitting (total)

What does the h represent?

Now we are set up for success!

a.) c = 4 + 11h

b.) c = charge for babysitting (total

h = number of hours babysitting

To answer part c we have to know where in our equation we should put the 3.

This is what we have so far to solve part c.

c = 4 + 11h

c = 4 + 11(3)

Do we have to solve an equation like in 0.1 or can we simplify by using the order of operations or a calculator.

This is what we have so far to solve part c.

c = 4 + 11h

c = 4 + 11(3)

c = 37

What is the unit of measure for the answer to part c?

Now we are set up for success!

c = 4 + 11h

c = charge for babysitting (total)

h = number of hours babysitting

To answer part d we have to know where in our equation we should put the 70.

This is what we have so far to solve part d.

c = 4 + 11h

70 = 4 + 11h

Do we have to solve an equation like in 0.1 or can we simplify by using the order of operations or a calculator.

This is what we have so far to solve part d.

c = 4 + 11h

70 = 4 + 11h

What should we do first to both sides of the equation as we try to isolate the h?

This is what we have so far to solve part d.

c = 4 + 11h

70 = 4 + 11h

66 = 11h

What should we do next to both sides of the equation as we try to isolate the h?

This is what we have so far to solve part d.

c = 4 + 11h

70 = 4 + 11h

66 = 11h

6 = h

What is the unit of measure for the answer to part d?
