3 T h is unit provides a context in which students deve l o pnumber and operation sense, learn to organize infor-mation in different forms and utilize the calculator asa tool that helps them solve complex pro b l e u r t h e r m o re, the unit serves as a vehicle for pra c t i c i n gestimation sk i l ls, working with decimals, fra c t i o ns, andra t i o s, and is a pre c u rsor for a unit on data collection. Students work in groups to create their supermarketsand to answer the group test, but during the rest ofthe assignments students may choose to work ing roups or individually.

4 Calculators are available at alltimes to ens u re that students can achieve the pre c i-sion needed to successfully complete all the Supermarket unit was created to address theneeds of students who believe they cannot do math and feel that math is dull, boring and irre l e va n t .T h is hands-on project, provides them with opportuni-ties to explore and solve pro b l e ms, using prior knowl-edge and/or acquiring new knowledge. It gives theman understanding of mathematics based on a familiarsituation students experience daily. The unit allowsstudents to dis c over that mathematics is re l e va n t ,i n t e resting and useful.

5 It also helps students deve l o pthe idea that they can be good at mathematics andsomething at which they can get a t e r i a l s : Newsprint paper Markers Scissors, rulers and glue Graph paper Calculators Lots of Supermarket advertisements (at leastone per student) Student Assignment handouts (see LessonPlans and Activities)Time LineEach Lesson takes a different amount of Lesson Plans and Activities for OutcomesThe concepts embedded in this Lesson are basedon the National Council of Te a c h e rs ofMathematics (NCTM) Standard s. Students will: u n d e rstand, re p resent and use numbers whole, fra c t i o ns and decimals in a variety off o r ms in re a l - world and mathematical pro b l e msi t u a t i o ns ; d evelop number sense and re l a t i o nships ofwhole numbers, fra c t i o ns and decimals ; u n d e rstand and apply ratios and pro p o r t i o ns ; u n d e rstand and appreciate the need for num-b e rs beyond whole numbers and compre h e n dh ow basic arithmetic opera t i o ns are related toeach other.

6 Systematically collect, organize and describedata using tables, Venn diagra ms and gra p hs ; d evelop an informal understanding of the dif-f e rent types of measures of central tendency(median, mode, and mean). Prerequisites: Teachers &S t u d e n t sThis unit is not meant to be an introductory les-son on graphs, ratios, fractions, decimals, , it was designed as a seventh-grade open-ing unit to review and practice general mathskills taught in earlier s s e s s m e n tAn assessment rubric is provided at the end ofthe Plans and ActivitiesA student assignment sheet is provided at the endof each Lesson in this unit for teachers to copy andd istribute to their class.

7 It is important to give stu-dents their own assignment page for them to us eas a guide and to help them work at their ownpace within the time frame of the Lesson . Note: These assignments were originally inEnglish and Spanish to address the needs of thisparticular school s large Hispanic population. Duallanguage assignment pages are available uponrequest to Susan 1: Creating a SupermarketTime:2 class periodsA c t i v i t i e s :In gro u p s, students are asked to create their own supermarkets from store adve r t is e m e n t s. Eve r ysupermarket must include the following cate-gories: dairy pro d u c t s, meat, fruit and ve g e t a b l e s,cleaning pro d u c t s, paper pro d u c t s, gro c e r i e s, bev-e rages and mis c e l l a n e o us.

8 Each category has toinclude at least five pro d u c t s, and each group hasto give its store an original name. Products maynot be repeated within each Supermarket and eachp roduct must have a picture, name and price. Allf i n ished supermarkets are disp l a yed around thec l a s sroom. If a group finishes early, the studentsmay include another category or Unit5 Student Assignment Sheet 1 (1 of 8 to be handed out to students)Using store ads, each group will create its own Supermarket will have to include the following category must have at least five different the picture, the name and the price of each your Supermarket an original dairy products2.

Students are to make a table that containsthe following headings listed in StudentAssignment Sheet # only their own gro u p s Supermarket , stu-dents are asked to re c o rd on their tables twop roducts from each category and find the h is table constitutes the student s first sh o p-ping list. (The teacher needs to model whatthe first table should look like and explicitly linkshopping lists to the table form.)

10 B. Students are asked to make a new table withthe same headings as in Part A. Using all thesupermarkets posted around the room, studentsa re asked to generate a shopping list with atleast six products that totals between $100 and$ 105. Next, students are to pre p a re a list wherethe total is between $200 and $202. For thisa c t i v i t y, students move around the classro o m , v isiting the different supermarkets and re c o rd-ing their shopping lis t s. If students finish early,as extra credit they may make an additional lis twith a total between $300 and $301.
