T5: Top Ten Teaching Tips with Technology
• Effectively using technology in the classroom is as much
about involving kids actively and encouraging them to think as it is about pushing buttons
or “bells and whistles”
T5: Top Ten Teaching Tips with Technology
• The pedagogy:• Demonstrate, Check• Make connections
• Numeric, symbolic, graphical• Visualize, see it another way
• Create suspense, surprise• Think, predict, analyze• Play games, have fun
T5: Top Ten Teaching Tips with Technology
#10 Starting class: Play “guess the function”
by “hiding” the equations in
Y8, Y9 or Y0

#9 Testing conjectures: • Student predictions
• Give the kid in the front row the overhead calculator
T5: Top Ten Teaching Tips with Technology
#8 Seeing patterns and asking students to guess and
check: • Using the home screen, tables
and the Ask/Ask setting

#7• Projecting onto a whiteboard
so you can “write” on the graphs; make it like a game
show• Using Horizontal and Vertical
lines in the Draw menu

#6
• Calling on your students randomly either with numbers
or names entered into a program

#5• Using the STO-> key to test hypotheses, use parameters, or
solve to check equations• Enter key to “pause” the graph
• typing over an equation to retrace for “instant replay”
T5: Top Ten Teaching Tips with Technology
#4• Showing families of curves
• (multiple graphs): • using a list (L1) as a
coefficient: • y = ax2 + bx + c
• y = L1x2 + bx + c
T5: Top Ten Teaching Tips with Technology
#3
• Preparing for class: • Using graph data bases (GDB)
to save functions and save time!
• (in the DRAW menu)
T5: Top Ten Teaching Tips with Technology
#2
• Using regular function notation
• Y VARS, e.g Y1(2) or Y1(x+2) to show variations and
transformations

And now the #1 technique!• Animating curves with parametrics and
polar curves;• “replaying” the action in real time (using
a stopwatch)• Use x=T, y=f(T) to animate any function;
• Using SIMUL and • SEQUENTIAL modes

•This wasn’t David Letterman, but I hope you enjoyed the presentation
and picked up something to enhance your classroom and help your students.
Thanks!
