Sunshine State Standards Benchmark:
    MA.5.2.2 – Add and subtract fractions and decimals fluently and verify the
       reasonableness of results including in problem solutions.
Common Core Math Standards:
    MACC.5.NBT.2.7: Add, subtract, multiply, and divide decimals to hundredths,
       using concrete models or drawings and strategies based on place value, properties
       of operations, and/or the relationship between addition and subtraction; relate the
       strategy to a written method and explain the reasoning used.
    MACC.6.NS.2.3: Fluently add, subtract, multiply, and divide multi-digit
       decimals using the standard algorithm for each operation.
Goal and Objective: Students will be able to add and subtract decimals given the real
world task (authentic) of buying groceries while staying within the confines of a budget.
Materials:
    “Name Brand” and “Store Brand” Grocery List. Provide one for each student and
       one for the teacher.
    Journal Prompt (see attachments). Provide one for each student.
    Self-Assessment Checklist (see attachments). Provide one for each student.
    Timer or clock (visible to the entire class).

Estimated Time: This lesson should last for 45 minutes to one hour.
Motivation: Most families must buy food and household items that they will need every
few weeks. Instead of randomly throwing things into a shopping cart and paying
whatever the total is, many families must stick carefully to a predetermine budget to buy
all of the items they need. A helpful way to make sure that you are able to buy
everything that they need is to use a list that is written before they go shopping. Florida
families must also determine if they will purchase “name brand” or “store brand”
products. Today, students will practice using a grocery list with a predetermined budget
as they add and subtract decimals.
Lesson Procedure:
      The teacher will gather all materials in advance.
      Next, the teacher will tell the students the benchmark, objective, and motivation
         for the lesson. The SSS benchmark may be displayed on the board (see
         attachments).
      Additionally, the teacher will inform the students the reason why they will
         participate in this lesson: “As many of you are aware when you go to the grocery
         store there are many choices to make about the items you will buy. Some items
         are “brand name” items and others are what are called “store brand” or “generic”
         items. Generally, “name brand” items cost more than “store brand” items. Many
         times the same manufacturer makes both products and then they are put into
         different packaging: the “name brand” and the “store brand”. Even though the
         items are not so different, many people have favorite “brand name” products that
         they use all the time rather than the “store brand” products. These might be their

       favorite products or a special treat. Take this time to ask a few students to share a
       favorite “brand name” product that their family buys at the grocery store with the
       class. However, many families must stick to a pre-written list and a budget when
       they shop. To be able to purchase everything that they need from the list, they
       must make decisions on whether to choose “brand name” or “store brand”
       products. Some families choose to buy all “store brand” products in an effort to
       save the most money. Other families may buy mostly “store brand” items, but as
       mentioned before, buy a few favorite “brand name” items. Still, other families
       may not buy any “store brand” items and choose to buy the “brand name” items
       instead. It all depends on what is on the list, the preferences of the family
       members, and how much money is in the shopping budget. Today you will be
       given a grocery list with choices for “brand name” and “store brand” items. You
       will choose which items to purchase based on the following criteria: you must
       purchase everything on the grocery list and you may not go over your budget by
       even $0.01, and you must purchase at least five (5) “name brand” products. You
       will work as teams or “families” to determine which items will be “name brand”
       or “store brand”. Keep a running total of how much your family is spending.
       You may have to make changes to your initial decisions. The skills learned in this
       lesson today will help you to make wise choices at the grocery store, just like
       thousands of Floridians do everyday.”
      The students will be separated into groups (mixed ability levels).
      The teacher will preview relevant (based on students’ prior knowledge)
       vocabulary with the students.
      The teacher will distribute the Grocery Lists with budgets.
       The teacher will instruct students to designate roles for each member of the team:
       Grocery Wrangler (insures that all items have been purchased, including the five
       (5) “brand name items, using “We’ve Got It” column on grocery list), Fact
       Checker (checks that everyone has added and subtracted correctly, and that totals
       are the same across the group), Time Management Specialist (makes sure that
       their group stays on task, not wasting valuable activity time), Motivator (keeps the
       group’s spirits up, is encouraging to team members during the activity,
       compliments outstanding work), Materials Maverick (makes sure that the group
       has all necessary materials throughout the task), Spokesperson (explains how
       group came to their total and the rationale for the items that were chosen), Scribe
       (writes the explanation, for the Spokesperson).
      Students are asked to try to complete the activity within thirty minutes. Extra
       time will be given for groups who have not finished at that time. The Time
       Management Specialist will keep the group on task.
      During the activity the teacher will circulate throughout the groups to scaffold
       where needed.
      After the thirty minutes is up, the teacher will say, “Thirty minutes has passed. If
       your group has finished, please raise your hand so that I may check your work. If
       your group has not finish, please continue to work. You have another five
       minutes.
      When all groups have finished and the teacher has checked their totals, the
       Spokesperson from each group will present their strategy to the class.

      Following the presentations, the students will complete the self-assessment and
       journaling activities.

Extensions: As students complete the activity they will be directed to write a reflection
to this math journaling prompt: If your total had been more than your budget, what
would you have done to be able to meet the budget amount? Several students may share
their answers with the class.

Assessment: The teacher will conclude the lesson by having students complete a self-
assessment checklist. The self-assessment, journal, and grocery list with totals will serve
as assessments to prove that students have met the lesson objectives.
Modifications:
     ELL: Illustrations of food items may be added next to the names of items on the
        Grocery Lists with Budgets. Additionally, a student dictionary may be used to
        label the food items in the student’s native language.
     Technology: Students may make their own shopping lists and budgets using word
        processing programs.
     Gifted: Gifted students may make software presentations of the Florida Food
        Round Up! process. They may make a presentation of their final product to the
        class. The presentation must include their solution to the journal prompt.
