Introduction
Set up the activity by telling your students:
The standard form for scientific notation is
a ¿ 10 n ,where a is greater than or equal to 1 and
less than 10, and n is an integer.
1. Have students practice writing the following
numbers in scientific notation using pencil and
paper.
a. 93 000 000 9.3 ¿ 10 7
b. 384 000 000 000 3.84 ¿ 10 11
c. 0.00000000000234 2.34 ¿ 10 -12
d. 0.0000000157 1.57 ¿ 10 -8
2. Have students change the following numbers into
scientific notation (SCI) using the
TI-34 MultiView scientific calculator.
a. 12 000 000 1.2 ¿ 10 7
b. 974 000 000 9.74 ¿ 10 8
c. 0.0000034 3.4 ¿ 10 -6
d. 0.000000004 4 ¿ 10 -9
Note:
Answers assume the default floating decimal setting.
3. Have students change the following numbers into
standard (NORM) notation.
a. 5.8 ¿ 10 7 58 000 000
b. 7.32 ¿ 10 5 732 000
c. 6.2 ¿ 10 -6 0.0000062
d. 3 ¿ 10 -8 0.00000003
