1) Find the number of coins in each bag:
Remember:

Each pouch contains the same number of $1 gold coins.

The total number of coins on each side of the equation is the same.
2) Write down your steps so that someone else could follow your steps to find the number of coins in a pouch.
3) Describe how you can check your answer. That is, how do you know you have found the correct number of gold coins in each pouch?

As a table group:
1) Use gold pouches & blocks to create each visual equation.
2) Complete steps 1, 2, 3 in your packet.
3) Look in the bag to verify that your answer is correct.

Challenge: In Visual Equation 2, Nichole thought of the left-hand side of the situation as having two groups. Each group contained one pouch and two coins.
She visualized the following steps to help her find the number of coins in a pouch.
Is Nichole correct? Explain.
Noah looked at Nichole’s strategy and claimed that she was applying the Distributive Property. Is Noah’s claim correct? Explain.

Are there other situations in which Nichole’s method might work? Explain.
