Develop Understanding

Today's Learning Goal: (G6, U6, L13)

Critique (orally and in writing) arguments that claim two different numerical expressions are equal.
Justify (orally and in writing) whether numerical expressions involving whole-number exponents are equal.

Today's Materials:

Laptop
Laptop charger
Pen/Pencil/Paper/Expo Marker (optional)

Please complete the Jump Start (activator). You have 5 minutes before we review. This is independent it should be silent.

Reminders:

1. Ready for class

2. No cellphones

3. Volume must be low.

4. Read and follow all directions

5.) Take your bag off and immediately begin the Activator.

When working with exponents, the bases don’t have to always be whole numbers. They can also be other kinds of numbers, like fractions, decimals, and even variables.

For example, we can use exponents in each of the following ways:

Andre and Elena knew that after 28 days they would have

coins, but they wanted to find out how many coins that actually is. Andre wrote:

Elena said, “No, exponents mean repeated multiplication. It should be, 28 x 28 which works out to be 784.”
