Culminating Assessment: Students will submit their cookie projects. Looking at the written plan for the decorated cookie, the written explanation and the finished project checks mastery for this lesson. The teacher will assess the student's understanding by using the following rubric.

Cookie Rubric:

Teacher Preparation: The teacher should request parents to bake a large sugar cookie for each child in the class. The teacher should also request items to decorate the cookies. This can include M&Ms, skittles, raisins, etc.

Activity one: 
Begin by reading the book, Alexander, Who Used to be Rich Last Sunday by Judith Viorst. After that, review the value of each coin. Next, ask the students what they have bought with a dollar. Write the students responses on an overhead. Discuss the differences in values of a dollar and a penny, dime etc. Have the students take out their bag of money and get with a partner. The partners will experiment several ways to make a dollar. The groups will record their answers on a sheet of paper. The teacher will monitor and assist as needed. After approximately 20 minutes, the students will pulled back to whole group to discuss their answers. Students will volunteer to share their answer by using transparency money on the overhead projector. The teacher will model adding the money on the overhead. The teacher will model checking the calculations by using an overhead calculator. The class will discuss different ways to group the money while adding. The class will also discuss equivalent amounts of money. For example, 1 dime or 2 nickels could represent 10 cents. www.aplusmath.com is a great site for students needing extra practice adding coins.

Activity Two: 
In whole group students will review the previous day's lesson, ways to represent a dollar. The teacher will relate the value of a dollar to real life experiences. Such as the questions; 'Can I buy a candy bar for a dollar? Can I buy a bike for a dollar? The student's responses to these questions will help the teacher observe comprehension of money concepts. The teacher will have a variety of objects with clearly marked price tags in the classroom. The students will make a list of how they would spend a dollar, writing their choices on the left side of a piece of paper and the price on the right side. Teachers should remind the students to add as they go and double check their answers. The students will be cautioned that they don't have to spend exactly one dollar, it may be less. After students make their lists they will take out their bag of plastic money and count out the correct amount. Students will be paired up to check each other's calculations with calculators. For added enrichment, practice or homework go to www.mathstories.com. This site gives word problems using money.

Activity Three: 
Begin this activity by reading If You Give A Mouse A Cookie. The teacher will explain to the students that they have a dollar to spend to decorate a cookie. The available toppings along with its price will be listed on a chart. Each student will have a planning sheet. (See attached sheet #1 and #2.) The students will then develop a decorating plan on their planning sheet. Calculators will be available for checking answers. The teacher will monitor and assist where needed. The teacher may pull an individual or a small group that seem to be having difficulties. When finished planning, a friend and the teacher will check planning sheets. Together the teacher and the students will correct any present errors. The students will then purchase the toppings using plastic money. Finally cookies will be decorated. When finished decorating, students will have a cookies parade where all their cookies and planning sheets are displayed so they can view their classmates decorated cookies. The class will discuss the similarities and differences of the decorated cookies. The class will discuss why it's important to understand the value of each coin and how to add money. Finally the students may eat their cookies. As a final activity students will write a reflection of this activity and what they learned.
