# Lesson 16 Our Market’s Inventory

## Warm-up Notice and Wonder: The Shopping Cart

What do you notice? What do you wonder?

## Activity 1 100 Items

You sell 3 kinds of items in a store. At the beginning of each day you have:

a total of 100 items

less than 10 of one of the items

more than 10 for the other 2

Choose 3 items to sell at your market. Write the names of the items in the first row.

Fill in the second row to show how much of each item you begin the day with.

Share your store set-up with your partner pair. Discuss:

the amount you have for each item

how you know that you have a total of 100 items at your store

names | item 1: | item 2: | item 3: |
---|---|---|---|
