Congratulations! Youve just ound your answer to the
question, What can I do to create real enthusiasm or
mathematics in all my students?
Created by teachers or teachers, the Math Academy tools
and activities included in this booklet were designed to create
hands-on activities and a un learning environment or the
teaching o mathematics to our students. On Math Academy
days I oten ound that I couldnt make it rom my car to my
classroom without being stopped by enthusiastic students
wanting to know every detail o the upcoming days events.
Math Academy days contributed to a positive school-wide
attitude towards mathematics on our campus.
This booklet contains theMath Academy Lets Go to the Mall!
Explorations in Combinatorics, which you can use to enhance your
math instruction while staying true to the academic rigor required
by the state standards ramework.
This eort would not have been possible without support rom
The Actuarial Foundation. With the help o the Foundations
Advancing Student Achievement (ASA) grant program, whichis committed to unding projects that enhance the teaching o
mathematics, this Math Academy program came into being.
I sincerely hope that you enjoy implementing theLets Go to the
Mall! Math Academy with your students. When you do, you will
nd that your students engage with mathematics on a whole
new level. The Actuarial Foundation is truly a great partner in
urthering mathematics education!
For the kids!

When the Math Academy concept was rst developed, it was designed as a hal-day or ull-day evenwhich allowed students to deepen their understanding o math while interacting with volunteersrom the community (see page 26 or ideas on working with community volunteers). The activities
we selected or these events were hands-on, standards-based lessons which applied mathematicalprinciples in real-world scenarios. Each student experienced three to ve activities during the courseo the event.
Each Math Academy began with a brie school assembly eaturing a guest speaker who representedthat days particular theme. Themes included math related to restaurants, sports, nature, shopping,ne arts and other topics, as well as ocusing on math-related careers. Ater the assembly, studentsrotated to dierent classrooms where they engaged in various activities related to mathematics andthe days coordinating theme.
Included in this booklet is the Math Academy Lets Go to the Mall! Explorations in Combinatorics,which has all the activities we used or the combinations and permutations Math Academy. ThisMath Academy is designed to help students understand the connection between various kinds ocombinations (multiplication principle and choose numbers) and permutations. You may choose toimplement a grade-level or school-wide Math Academy as we originally designed it, or you may preerto implement these activities in your own classroom. Whichever ormat you use, keep in mind thatthe goal is to help your students see the relevance o mathematics in real-lie contexts. I you wouldlike more inormation on the set-up or a school-wide or grade-level Math Academy event, visit The

Math Academy Format
You may choose to conduct your Math Academy as a school-wide event, as agrade-level rotation, or as a single-classroom experience. I you will be holding
your Math Academy or a single classroom, you may want to invite a guestspeaker to speak with your class about how mathematics is used in his/her job(rather than putting on a school-wide or grade-level assembly as described below).
Math Academy Schedule
Schedule and times may vary depending on format being used.
Opening assembly (optional) 15 minutes
Directions and Math Journals 15 minutes
Activity Rotations 3045 minutes per activity
Assessment and Closure 15 minutes
Opening Assembly/Directions
To build enthusiasm and to ocus attention, have everyoneparticipate in the Math Academy Chant(or younger students):
You and me, we all agree Math is un as you will see!It makes us think, it makes us strong,It helps us learn even when were wrong.
You and me, we all agree
Math is un at the Math Academy!inoucon
Announce to the students that today they will be workingon projects dealing with combinations and permutations.
Gues Seake pesenaon (oonal)
Beorehand, arrange or someone in the sales industry to talk to thestudents about the mathematics in the mall (they may or may notconnect to combinations and permutations, but encourage them todo so). Possible guest speakers may include someone rom the mall,ice cream shop, clothing shop, or any retail store. Although thisguest speaker will primarily be ocused on the shopping side o
this Math Academy theme, you may want to work with him/herahead o time to assist with tying in mathematical ideas to the talk.
Use o Math Journals
Students record their ndings in their Math Journals during each activity.These journals should contain all recording sheets or the activities as wellas blank paper or the extension activities. Beore beginning the ActivitiesRotation, students should spend about 10 minutes writing in their math jour-nals, including their refections rom the assembly as well as briefy describing
what they already know about combinations and/or permutations.

Activities Rotation
I multiple classes are participating in the Math Academy, eachclassroom should host a dierent activity so students will rotaterom classroom to classroom in order to complete each activity.I only one class is participating, the students may rotate romone activity to the next around the room, or they may do eachactivity as a whole class, one activity ater the other. Activitiesbegin on page 7. For best results, plan on three to ve activitiesor your Math Academy.
Closure and Assessment
Once all activities are completed, the students may return to theirhomeroom classes or nal refections and assessment. See pages 22and 24 or sample quiz and survey.

Gettng Started (continued)
We asked our students to use
graphic organizers to recordtheir thoughts and ndingsin their math journals. Thiscreates a great connection toour language arts curriculum.
The best results are achievedwhen 45 minutes are allowedin each classroom about 30minutes or the activity and15 minutes or clean-up andrefection. The students can
use their math journals torecord their ndings during theactivities and write refectionson the journals blank pages.

Mat Actty 2:Be a Sport with Combinations
Objective The students will determine combinations using choosenumbers while discovering, identiying, recording, and
verbalizing the arithmetic patterns or various choose-numbercombinations. The students will model their results as anorganized list on a chart.
Materials Pencils
Clear bags or paper manipulatives
Paper manipulatives copied, cut and placed in plastic bags(see page 13)
The Big Sale combinations sheet or each student(see page 14)
Procedures 1. Optional: Set the stage or the Be a Sport store put asign on the outside o your door, decorate your room, and/or dress up like someone working at a sports apparel store.
Copy and cut apart the paper manipulatives and put in2.clear bags. Note: Be sure to include more o each item thanis needed so that students must think about when to stopputting combinations together.
Discuss the problem with the students (see Be a Sport3.combinations sheet). Explain that the store is having a2-item special. Each customer may select exactly two items(must be dierent) and put them in a bag. Their job is to
discover how many dierent bags can be made when select-ing two items rom six choices.
Demonstrate how to select exactly two items rom the six4.choices. Emphasize that the two items may never be identical(e.g.: they cannot select two baseball hats at the same time).
Have students work in groups to create all o the possible5.2-item specials by selecting exactly two unique items oreach bag.
Once groups are nished, demonstrate how to represent all6.o the combinations using a chart or organized list.
Have students create their own charts and/or organized7.lists to demonstrate their results.
Closure discuss why there are exactly 15 possible8.combinations.

Ideas orCustomizing
This Activity
Have students create a tree diagram to illustrate theircombinations rather than an organized list.
Change the number o items being used and/or the num-
ber o items being chosen (start with 6 items and choose 1,2, 3, 4, 5, or 6; start with 5 items and choose 1, 2, 3, 4, or5; start with 4 items and choose 1, 2, 3, or 4; start with 3items and choose 1, 2, or 3; start with 2 items and choose1 or 2; start with 1 item and choose 1).
Ask students to create a chart or diagram to show the patternsor each o the combinations created in the above option.
Discuss how choose number combinations dier romthe multiplication principle combinations (lessons one inthis booklet).
Ask students to look or patterns when organizing their
combinations.
Ask students to derive an algorithm or determining thenumber o combinations possible.
Change the number o items available.
Advanced: Develop the ormula or nding choose num-bers. The ormula or nding choose numbers is rarelytaught in middle school. The beauty o this problem ormiddle school students is in allowing the students theopportunity to visualize, identiy, and verbalize patterns.However, i you choose to introduce the ormula, you will
want to be sure they are already very amiliar with actorials.
In= number o items available and t= how many itemschosen, then the ormula will be as ollows:
n!
(t!)(nt)!
Te Famos handsake problem
This widely-used scenario has beenused in mathematics classes ormany years. Ask the student: I agroup o people got together andeach person shook the hand oevery other person in the groupexactly one time, how many hand-shakes would take took place? Thetable below shows the answers:
# of eole
n gro # of andsakes2 1 (1)
3 3 (2+1)
4 6 (3+2+1)
5 10 (4+3+2+1)
6 15 (5+4+3+2+1)
This is another example o choosenumbers. In this case, no matterhow many people are in the group,two people are chosen at a timeto shake hands. You may want tohave the students act this out.

The sports apparel store at the mall, Be a Sport, is having a great sale this weekend!Each customer may choose exactly two items rom the list and purchase them bothor a great price. The trick is that each 2-item special must have two dierent items
(or example, they may not purchase two T-shirts at the same time).
What are all the dierent combinations that can be made by choosing exactly two items?
Use the paper items to discover how many combinations are possible (remember, you may not put two o the sameitem together). Then make an organized list in the chart below to show all the possible combinations. Use words,numbers, and pictures to demonstrate/explain how you arrived at your answer.

One o the most benecial aspects o our Math Academy program is theactuarial mentors/volunteers who interact with our students during each
Math Academy activity. Our actuarial mentors take time away rom theirusual work responsibilities on the days o our events so they can help out inthe classrooms. Please take the t ime to contact The Actuarial Foundation atmathacademy@actfnd.orgto nd out i actuaries are available in your area.
I you do not have actuaries available in your community, you may want toconsider requesting the assistance o parents, community members, or businesspartners who would be willing to work with the students during the activities.
Ater securing your mentors/volunteers, it is critical to identiy a Lead Mentorwho will serve as the liaison between you and the other mentors. The Leadshould e-mail all communications rom the teachers to the mentors, set up
schedules, send reminders beore each event, etc.

According to the NCTMPrinciples andStandards, the main topics o discrete mathematics are distributedacross the Standards instead o receiving separate treatment, and theyspan the years rom pre-kindergarten through grade12. As an activebranch o contemporary mathematics that is widely used in business andindustry, discrete mathematics should be an integral part o the schoolmathematics curriculum, and these topics naturally occur throughout theother strands o mathematics.
Although the content or combinatorics is integrated throughout theNCTM content standards, the ollowing pK-12 process standards arespecically addressed in this booklet:
Problem Solving:
Build new mathematical knowledge through problem solving
Solve problems that arise in mathematics and in other contexts
Apply and adapt a variety o appropriate strategies to solve problems
Monitor and refect on the process o mathematical problem solving
Connections:
Recognize and use connections among mathematical ideas
Understand how mathematical ideas interconnect and
build on one another to produce a coherent whole
Recognize and apply mathematics in contexts outside o mathematics
Representation:
Create and use representations to organize, record, and communicatemathematical ideas
Select, apply, and translate among mathematical representations to solveproblems
Use representations to model and interpret physical, social, and mathemati-
cal phenomena
You will want to check with your own state ramework
