It was almost the last day of school and Lauren wanted to give her teacher, Ms. Jane a special gift. She saw a beautiful Orchid at the store and knew that it was the perfect present. Lauren’s mom read the price tag, “the cost of this plant is fourteen dollars.” Lauren only had five dollars and she started thinking of a way that she could add to her money and pay for the Orchid.

Have you ever made a purchase with your own money? How do you think Lauren can earn more money to buy the gift?

Lauren thought about all of the different ways she could increase her amount of money. A Car wash? Dog Walking? Yard work? Finally, she decided she would set up a lemonade stand at the end of her street. June is a hot summer month and surely people in her neighborhood would enjoy sweet, refreshing lemonade! Lauren made a list of all the materials she would need. She needed to buy a sign to attract customers and she also needed to buy plastic cups to give her customers. Her mom gave her all of the other supplies she needed from the kitchen. Lauren used her five dollars to pay for a sign and cups at the store for a total of two dollars.

Lauren wanted to ADD TO her money, but instead she had to TAKE FROM her money. Lauren started off with $5.00 and she had to take $2.00 away. How much money does she have now? Turn and talk to
