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. The fold crease 3. Use scissors to cut along your drawn line, but ONLY to the crease!

Foldable 4. Write EXPONENTS down the left hand side The fold crease

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? 2 1 = = 2 7

Negative Exponents Negative Exponents To find the value of negative exponents, take the reciprocal make the exponent positive, then evaluate (solve)! For example: 2 -2 = 1 2 = 1 4 Take the reciprocal Make the exponent positive Evaluate You Try!!! 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 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. The fold crease 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: 5 0 =1(-3) 0 =1

Exponent Investigation Back to the foldable! Let’s write a rule for zero exponents!

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

Foldable 7. On the left hand section, write an example of a zero exponents. 8. On the right hand side, write an explanation of the exponent rule. Example Rule Example Rule
