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
amount at the beginning of the day
amount at the end of the day
