Memorial High School is equipping its math department with new graphing calculators to help students learn mathematics concepts and be successful on standardized tests. The new TI-NSpire calculators will provide students with tools to model mathematical situations, solve problems using multiple representations and approaches, and reduce test anxiety. Teachers will be trained on using the technology to reinforce operations and help students who are deficient in particular areas.

4. §111.31. through 111.37. (a) Basic understandings.
Implementation of Texas Essential Knowledge and Skills for
Mathematics, Grades 9-12.
The provisions of this subchapter shall be implemented beginning with the 2006-
2007 school year. This implementation date shall supersede any other
implementation dates found in this subchapter.
Tools for algebraic thinking.
Techniques for working with functions and equations are
essential in understanding underlying relationships. Students use a
variety of representations
(concrete, pictorial, numerical, symbolic, graphical, and
verbal), tools, and technology (including, but not limited
to, calculators with graphing capabilities, data collection
devices, and computers) to model mathematical situations to solve
meaningful problems.
Underlying mathematical processes. Many processes underlie all
content areas in mathematics. As they do mathematics, students
continually use problem-solving, language and communication, and
reasoning (justification and proof) to make connections within and
outside mathematics. Students also use multiple
representations, technology, applications and modeling, and
numerical fluency in problem-solving contexts.

5. Teachers using Technology to support
TEKs-TAKs-STAAR
Provide ways to help students that
are deficient.
Reinforces operations with real
number.
Use multiple context to solve
problems; Write, graph, and solve
functions.
Lessen students frustration and
anxiety.
Help students focused on the
lesson longer periods of time.
Help students to retain
information and feel confident
about accuracy of their answers
which lead to
Student being successful on state
test

6. Basic Calculator FAQ
Q: Why calculator will not turn on?
A: Press 2nd key and blue up arrow, window screen resolution
may be diminished . Then try replacing batteries
Q: How do I change the language back to English?
A: Press the purple APPS key, scroll down to you see language
English and press enter
Q: Why won’t the graph show ?
A: Make sure the equal button is highlighted in y= menu, press
zoom “0” to refocus the window or manually redo window in the
window menu by changing x min-max, x-scale, and y min-max, y
–scale.
A: Sometimes turning off the plots from the y= menu too!
Q: How do I restart the calculator to default settings?
A: Press the 2nd key followed by 7 1 2 enter, done verifies it has
been reset.

9. Methods For Equations-Expressions
1. Boolean test placed on the home screen an equation
Example: 2x+10=20 answer choices are a. 1 b. 2 c. 5 d. -6
A.“0” not a solution, “1” solution. Press 2nd parenthesis to get {}, 2nd Math for =
B. home screen 2{1,2,5,-6} +10 = 20 press enter {0,0,1,0} so, c. 5 is the correct
2. Equation Solver Press Math key then “0” equation solver shows up on the home
screen and you are now in a application, not the home screen.
A. This menu all equations are set equal to “0” by default so, 2x+10-20
B. Place equation, press enter, place a value for x= -1, press alpha enter, correct x=5,
C. press up arrow, place a new equation repeat steps A and B or 2nd Mode to exit.
D. Quadratic answers have two possible solutions so use x=1 then x= -1 to get all
possible answers.
3. Y= menu multiple representation with connection to graphs, tables, & function rules.
A. Place any one variable equation, function, or expression in y1=, 2nd graph for values
B. Place 2x+10 in y1= and 20 in y2=
C. view table y1= y2 is solution or
D. 2nd trace 5 enter 3 times it show the graph intersection.
E. Graph with trace key on to see graph that match identically -0 y1= menu
