1.

Have you checked SKYWARD? My grades are due APRIL 17th. Several of you are not doing well and need to make up any ZEROES next week. I am LIVE everyday at 1:00 for help.

a)

Yes, I sure have

b)

No, but I am

c)

I am right now

d)

Will do after this quizizz

2.

Did you watch the VIDEOS FIRST?

a)

Yes, always

b)

No, I better go back

c)

Sometimes

d)

Not at all and that's why I am not doing well

3.

The formula for the Area of a Trapezoid is?

a)

 b x b x h2\frac{b\ x\ b\ x\ h}{2}   

b)

 (b1 + b2)h2\frac{\left(b1\ +\ b2\right)h}{2}  

c)

 b x h2\frac{b\ x\ h}{2}  

d)

b x h

4.

 (b1 + b2)h2\frac{\left(b1\ +\ b2\right)h}{2}  What would I do FIRST to find the area of this trapezoid according to the video and formula?

a)

multiply the height

b)

divide by 2

c)

add the bases

d)

subtract the bases

5.

Yes, you add the bases FIRST. A diagonal is NEVER a base or the height so we don't need that 5. We need the top 5 and bottom 8 which equals WHAT when we add them?

a)

11

b)

14

c)

15

d)

13

6.

 (b1 + b2) h2\frac{\left(b1\ +\ b2\right)\ h}{2}  You get 13 when you add the bases. After we add the bases, what is our next step according to the formula?

a)

multiply the sum by the height

b)

add the bases

c)

divide by 2

d)

subtract the bases

7.

 (b1 + b2)h2\frac{\left(b1\ +\ b2\right)h}{2}  Yes, you multiply the sum of the bases by the height. Remember, since the h is backed up to the ( ), that always means to multiply. What is the height in this picture?

a)

5

b)

5

c)

8

d)

4

8.

Yes, the height is 4, so if the sum of the bases equals 13, what is 13 x 4?

a)

42

b)

52

c)

54

d)

62

9.

 (b1 + b2)h2\frac{\left(b1\ +\ b2\right)h}{2}  Yes, 13 x 4 is 52. Now that we added the bases FIRST and multiplied that by the height SECOND, what is the LAST step we solve?

a)

divide by 2

b)

add the bases

c)

multiply by the height

d)

subtract the bases

10.

 (b1 + b2)h2\frac{\left(b1\ +\ b2\right)h}{2}  Yes, we divide by 2 LAST. We got 13 when we added the bases FIRST. Second, we multiplied 13 by 4 and got 52, and LASTLY, we will take 52 and divide by 2, which equals what?

a)

57

b)

36

c)

26

d)

16

11.

 (b1 + b2)h2\frac{\left(b1\ +\ b2\right)h}{2}  The AREA for this trapezoid is 26. First, we added the bases and got 13. Next, we multiplied 13 by the height of 4 and got 52. Lastly, we divided 52 by 2 and got 26. How do you feel about AREA OF TRAPEZOIDS TODAY?

a)

GREAT, I TOTALLY GET IT

b)

BETTER THAN YESTERDAY

c)

OKAY

d)

NOT SO GREAT

12.

NOW LET'S PRACTICE! What is the AREA of this trapezoid? (b1 + b2)h2\frac{\left(b1\ +\ b2\right)h}{2}  

a)

176

b)

22

c)

88

d)

48

13.

What is the AREA of this trapezoid? (b1 + b2)h2\frac{\left(b1\ +\ b2\right)h}{2}  

a)

32

b)

11

c)

44

d)

22

14.

What is your favorite thing to do on Easter?

a)
