Algebra I End-of-Course

ExamChanging the way we teach.

“Why can’t we just teach the way I was taught? It worked just fine

for me!”Jim

That was then…

This is now!

So why can’t we just teach the way we

were taught?

• What if doctors continued to practice the same way they did 30 years ago?

• What if athletes trained the same way they did 30 years ago?

• What if computers processed the same way they did 30 years ago?

• What if movies looked the same way they did 30 years ago?

So what do these activities have to do with the Algebra I EOC?

Putting It All Together

Look at the data on the following released TAKS items covering Domain & Range.

• What observations can you make about students’ understandings and misunderstandings?

• How do the data support your observations?• What classroom experiences can we provide

to clear up misunderstandings?

14. The graph shows the path of a golf ball.What is the range of this function?

F. 0 < y < 100

G. 0 < y < 100

H. 0 < x < 5

J. 0 < x < 5

Objective 2: A.2B TSIET identify mathematical domains and ranges and determine reasonable domain and range values for given situations, both continuous and discrete.

2003 TAKS Grade 10th #14F: 16%, G: 50%*, H: 25%, J: 9%

*correct answer

27. What is the domain of the function shown on the graph.

A. -3 < x < 3

B. -3 < x < 3

C. -5 < x < 4

D. -5 < x < 4

Objective 2: A.2B TSIET identify mathematical domains and ranges and determine reasonable domain and range values for given situations, both continuous and discrete.

2004 TAKS Exit #27A: 31%, B: 44%*, C: 13%, D: 12%

*correct answer

Objective 2: A.2B TSIET identify mathematical domains and ranges and determine reasonable domain and range values for given situations, both continuous and discrete.

12. Mr. Maxwell asked his students to identify the domain represented by the function graphed below.

Which of the following student responses is correct?
