Changing 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?

Differences between TAKS and EOC
Current coverage of Algebra I TEKS
• TAKS grade 9 covers about 74% of Algebra I TEKS
• TAKS grade 10 covers about 90% of Algebra I TEKS
• TAKS exit level covers about 90% of Algebra I TEKS
• Algebra I EOC assessment covers about 95% of Algebra I TEKS

Exploring Objective 2:
Demonstrate an understanding
of the properties and attributes
of functions.
Algebra I EOC
Coming soon, to a campus
near you!
y
Frame the
top and
bottom
boundaries
of each
graph to
help you
find the
possible
y-values
(the Range).
x
Frame the left and right boundaries of each graph to help
you find the possible x-values (the Domain).
Work with your partner to find & record
the Domain and Range of each card.
Domain: - 2  x  2
Range: - 3  y  3
Domain: - 3  x  1
Range: - 2  y  2
Domain: - 3  x  
or x  - 3
Range: - 1  y  
or y  - 1
Domain: - 2  x  4
Range: - 3  y  2
Domain and Range Puzzler
You will need…
• One set of puzzler cards for every 2 people
• One Coordinate Grid Mat for every 2 people
• A “Puzzler #1” recording sheet for each person
Find two puzzler cards that can be used to create
a graph with each given Domain and Range. You
may use the cards more than once.

Putting It All Together
So what do these activities have
to do with the Algebra I EOC?
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?
Objective 2: A.2B TSIET identify mathematical domains and
ranges and determine reasonable domain and range values for
given situations, both continuous and discrete.
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
