Lesson 1: Hockey Time Concept/Topic to Teach: Students will tell, write, and calculate elapsed time.

Standards Addressed: Standard 3.MD.1: Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.

General (s) – Expected Outcome:  Students will be able to measure time in minutes and be able to solve problems that involve adding and subtracting time in intervals of minutes and or seconds.

Specific Objectives:  Students will use hockey situations to solve problems adding time intervals.  Students will use hockey situations to solve problems subtracting time intervals.  Students will tell time on a digital clock.

Introduction: Pass out 5-minute math task. Introduce concept of game time. Show a scoreboard clock counting down, perhaps a video highlight of the end of an exciting game. Draw attention to the game clock and discuss how it is different from a classroom clock? Ask Whole Group Problems: 1. In hockey, players come on and off the ice a lot. In last night’s Bruins game, Zdeno Chara played more than any other Bruin. During the first period, he played 9 minutes and 30 seconds. During the second period, he played 10 min. and 10 seconds, and during the 3rd period, he played 11 minutes and 47 seconds. How much total time did he spend on the ice? 2. The Canadians scored with 7:43 left on the clock in the 3rd period to tie the game. The Bruins then scored the game-winning goal with 2:54 left on the game clock. How much time passed between the goals? Share solutions and discuss after each problem. Problems are designed to be easy and give an introduction to the skill. Have the students work in small group on problem set #1 and then share the solutions with the group.

Lesson 3: Bruins Attendance

Concept/Topic to Teach: Rounding to 10 and 100

Standards Addressed: Standard 3:NBT:1: Use place value understanding to round whole numbers to the nearest 10 or 100.

General Goal(s) – Expected Outcome:  Students will round large numbers in the thousands and ten thousands to the tens and hundreds place.

Specific Objectives:  Students will identify and read numbers up to 25,000.  Students will round real attendance figures to the tens place.  Students will round real attendance figures to the hundreds place.  Students will round for the purposes of estimation.

Introduction: Pass out 5 Minute Math task. Watch video clips of large crowds, preferably hockey or Bruins games in the TD Garden. Ask the children to guess at the attendance. Check out pictures or videos of large stadiums from different sports (Most clips can be found on YouTube). Examples, Michigan Stadium, University of Michigan, Gillette Stadium, Foxboro, MA, Fenway Park, Boston, MA, and TD Garden, Boston. Talk about capacity and the size of the numbers being discussed and how it would be hard to add and subtract them. Introduce Rounding by rounding some real figures to the nearest hundred and adding them to see how much easier it is. To the whole class, ask the following two questions: 1. During 5 Bruins games in 2011, the home attendance figures were 24,359, 24,452, 24,189, 23,987, and 24,657. Round each number to the hundreds place. Add the new numbers together. What is an estimate for the attendance over those 5 games? Share strategies and solutions together. 2. The Bruins players work very hard in practice in order to be in shape for games. They put in lots of time each week in the exercise gym. Look at the list of 4 Bruins players. It shows how many minutes they spent exercising in a week. How many minutes did they spend in the gym altogether? Round the numbers to the tens place before adding in order to get a quicker estimate of the time that they played. In pairs or trios students will complete the sheet titled, ‘Rounding Problems’. Share some solutions with the group. Pass out Exit Ticket.

Differentiated Instruction: Adaptations (For Students with Learning Disabilities)  Pre-round some numbers, making it easier. Leave only one or two to do out of each set.  Offer the chance to use a calculator for the adding so they can focus on rounding. Extensions (For Gifted Students)  Ask them to round to different places. Give more advanced problems for estimating.  Offer the chance to use a sheet of statistics to create and solve their own problem.

Lesson 4: Help Your Favorite Bruin

Concept/Topic to Teach: Multiplication Problem Solving

Standards Addressed: Standard 3.NBT.3: Multiply one-digit whole numbers by multiples of 10 in the range 10–90 (e.g., 9 × 80, 5 × 60) using strategies based on place value and properties of operations. Standard 3.OA.1: Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7. Standard 3.OA.3: Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.1 Standard 3.OA.4: Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = _ ÷ 3, 6 × 6 = ?

General Goal(s) – Expected Outcome:  Children solve problems in which popular Bruins players need help solving problems involving multiplication.

Introduction: Pass out 5-Minute Math Task. Stress the existence of repeating groups in hockey. Assemble many groups of hockey items: skates, sticks, pucks, etc. To the whole class, ask and discuss solutions to the following two problems: 1. Tuukka Rask uses 3 rolls of tape every game. If he plays 4 games on a road trip, how many rolls of tape would he need to pack? 2. Patrice Bergeron and David Krejci are in the running for player of the week. The award will go to whoever scores the most goals. Krejci scored 2 goals in each of his 4 games last week Bergeron scored 3 goals in each of his 3 games. Who scored more goals in the week and won the award? Instruct the class to work with a partner to complete the problems below. Show all work and draw diagrams when possible. Afterwards discuss solutions. Then pass out the Exit Pass.  Tuukka Rask wants to know how many saves he made in the last week. He played 4 games. He averaged 30 saves in each game. How many saves did he make?  If Patrice Bergeron scored an average of 2 hours per day over the 7 days last week, how many goals would he score?  4 players go to dinner after the game, and order shrimp. If they each eat 9 shrimp, how many did they eat in all?  Challenge problem: David Krejci scored lots of game winning goals. If he scored 1 game winner every 11 games, how many would he score if he played in 77 games?
