### BostonBruins eNotebook

1. 1. By: Melissa Coughlin
2. 2. The sport of hockey has a lot ofconnections to mathematics. For this projectI decided to focus on my favorite team, theBoston Bruins. Four of the NCTM Standards:number and operations, measurement, dataanalysis and probability, and geometry canbe studied by examining aspects of theBruins and the game they play.
3. 3.  The Bruins have 24 players on their roster 14 of these players are forwards, 8 are defensemen, and 2 are goalies.  Represented as fractions this means: ▪ 14/24 or 7/12 of the team plays forward ▪ 8/24 or 4/12 or 1/3 of the team plays defense ▪ and 2/24 or 1/12 of the team plays goal  7/12 + 4/12 + 1/12 = 12/12 or one whole team!
4. 4.  The TD Banknorth Garden, the home of the Boston Bruins, can seat 17,565 fans for a hockey game. That means every student at St. Mike’s could fit in the arena, nine times over!  The decimal equivalent of 17,656 thousands is 1.7565 ten thousandths.
5. 5.  A goalie’s save percentage is a statistic that expresses a goalie’s success based on the number of shots he faces. Tim Thomas’s current SV% for the 2011-2012 season is .931 and Tuukka Rask’s is .906 This means that written as a percentage Tim Thomas has saved 93.1% of the shots he has faced and Tuukka Rask has saved 90.6% of the shots he has faced.
6. 6.  In hockey, the length of a player’s stick depends on the height of the player. Zdeno Chara, the captain of the Boston Bruins is the tallest player in the NHL at 6’9’’ tall and uses a stick that is 65 inches long. There are 12 inches in a foot and 2.54 centimeters in an inch  Therefore, the length of Chara’s stick is 65 inches, 165.1 centimeters, or 5 feet and five inches long (taller than me!) 5’5’’
7. 7. The Mathematics of an Ice Surface
8. 8.  To find the approximate area of the ice surface that the Boston Bruins play on use the formula for finding the area of a rectangle  Area of a rectangle = length x width The length of the ice surface is 200 feet and the width is 85 feet  200 feet x 85 feet = 17,000 square feet The Bruins have approximately 17,000 square feet of ice to skate on
9. 9.  Angles are very important in hockey, the boards are used as if they are another player on the ice. Use of angles video Lucic passes the puck to Chara off the boards at an angle
10. 10.  An ice surface has five faceoff circles, one at center ice and two in each zone. All of the faceoff circles have a radius of 15 feet, meaning that they are congruent. 15 feet
11. 11.  The Boston Bruins of 2010-2011 won theStanley Cup The base of the Cupis a cylinder  A cylinder is defined as having straight parallel Lines and a circular or oval section
12. 12. “Attack the triangle”Defenseman Joe Corvo’s stick forms a triangle with the ice and his body. Clarke MacArthur of the Toronto Maple Leafs is attacking this triangle in an attempt to knock Corvo off the puck.
13. 13. 8G 7 Opponento 6 San Josea 5l 4 Montreals Montreal2 3 OttowaF 2o 1 Torontor 0 A bar graph can be used to display the number of goals the Bruins scored in each of their last five games this season. Bar graphs are great for showing chronological data.
14. 14. Forward Goals Scored this SeasonSeguin 7 Using this data setLucic 6 for the number ofBergeron 7 goals each forwardKelly 3 on the Bruins hasPeverley 3 scored this seasonMarchand 2 the median numberHorton 2 of goals can beKrejci 2 found. The median isThornton 0 the value lying at theCampbell 1 midpoint of a set ofPaille 2 numbers. In thisPouliot 0 case, the median is 2Caron 0 goals.
15. 15. Penality Minutes This pie chart represents the penalty minutes for Seguin each player on the Bruins so Lucic far this season. Bergeron Chara Kelly The advantages of pie Peverley charts are that they visually Marchand show the parts (each Ference player’s penalty minutes) of Horton a whole (total penalty Krejci Corvo minutes). Boychuk Thornton The disadvantages are that Seidenberg they can be visually Campbell overwhelming and McQuaid Pouliot confusing to look at when Caron they are used to represent a large amount of information.
