Transcript Foldable

Foldable
1. Take out a piece of
notebook paper and
make a hot dog fold
over from the right
side over to the pink
line.
Foldable
2. Now, divide the right
hand section into 2
sections by drawing 1
line in the middle .
3. Use scissors to cut
along your drawn line,
but ONLY to the crease!
The fold crease

4. Write EXPONENTS
down the left hand side

VOCABULARY
Reciprocal: The reciprocal of a number is
found by dividing 1 by that number or
simply flipping the fraction over.
For example:
How do we
write whole
numbers as
fractions?

1
1 = 3
2 = 7
7

Negative Exponents
To find the value of negative exponents, take
the reciprocal make the exponent positive,
then evaluate (solve)!
For example:
You Try!!!
2-2= 1 = 1
22
4
Take the
reciprocal
Make the
exponent
positive
Evaluate
A.3-3
B.4-2
Exponent Investigation
• Evaluate the following expression.
• Write the following expression in expanded
form:
• What do you notice about the expanded
form?
Exponent Investigation
• Write each of the following in expanded
form. Then write the expression using a
single exponent.
1.
2.
Back to the foldable! Let’s write a rule for negative
exponents!
Foldable
5. Fold over the top cut
section and write
“negative exponents”
on the outside.
6. Reopen the fold.

Foldable
7. On the left hand
section, write an
example of a negative
exponents.
8. On the right hand
side, write an
explanation of the
exponent rule.
Example
Rule
Zero Exponents
Any number to the zero power is equal to 1.
For example:
50=1
(-3)0 =1
Exponent Investigation
Back to the foldable! Let’s write a rule for zero
exponents!

5. Fold over the top cut
section and write “Zero
Exponents” on the
outside.
6. Reopen the fold.
