Have the students work in groups to promote
discussion. Have them enter a table of data from the
student activity sheet into the data editor by using
v
.
Notice there are three lists available: L1, L2, and L3.
Discuss that they will enter fractions using the
P
key. Shown is an example of entering the family of
fractions with the denominator of 8.
Have students enter the conversion of fraction to
decimal to validate their work. With the highlighted
area in L2, press
v to see a menu. Add the
conversion L1
´f ¶d to define L2 as the decimal
representation of L1.
Add input to L1 to see L2 update automatically with
the output value of the conversion. Scroll to an open
entry space in L1. Students can enter more fractions
as a time saver. The students can create a running
list of all fractions in the activity instead of setting
up the calculator separately for each table.
To see the conversion again, scroll to L2 and press
v "
1.
Before starting the group investigation on the
student activity sheet, have the students clear any
data in the lists from previous use.
