The Value of Place Value (Continued) Continuing the Investigation Connect the place-value patterns to money. For example, ask students: • If each one of your "jelly beans" costs a penny, how many pennies would you spend for 1,314 jelly beans? 1,314 pennies. • How many dimes (tens) would you spend? 131 dimes and 4 more pennies. • How many dollars (hundreds)? 13 dollars, plus 14 more pennies, or 1 dime and 4 pennies. Older students can record the money (and enter it into the calculator) in decimal form, 13.14. Then they can use the calculator to connect dimes to one tenth (0.1) of a dollar ($13.14 has 131 dimes or tenths) and pennies to one hundredth (0.01) of a dollar ($13.14 has 1314 pennies or hundredths). For older students, connect the place-value patterns to conversions between metric units. For example, a measurement of 324 centimeters can also be recorded as 32.4 decimeters (or rounded to 32 dm) because 1 dm = 10 cm, or it can be recorded as 3.25 meters (or rounded to 3 m), because 1 m = 100 cm. © 2000 TEXAS INSTRUMENTS INCORPORATED TI-15: A Guide for Teachers 31

The Value of Place Value
(Continued)
Continuing the Investigation
Connect the place-value patterns to money. For
example, ask students:
•
If each one of your “jelly beans” costs a penny,
how many pennies would you spend for 1,314
jelly beans?
1,314 pennies.
•
How many dimes (tens) would you spend?
131 dimes and 4 more pennies.
•
How many dollars (hundreds)?
13 dollars, plus 14 more pennies, or 1 dime and 4
pennies.
Older students can record the money (and enter it
into the calculator) in decimal form, 13.14. Then they
can use the calculator to connect dimes to one tenth
(0.1) of a dollar ($13.14 has 131 dimes or tenths) and
pennies to one hundredth (0.01) of a dollar ($13.14
has 1314 pennies or hundredths).
For older students, connect the place-value patterns
to conversions between metric units. For example, a
measurement of 324 centimeters can also be
recorded as 32.4 decimeters (or rounded to 32 dm)
because 1 dm = 10 cm, or it can be recorded as 3.25
meters (or rounded to 3 m), because 1 m = 100 cm.
