MeanRoll 6 dice and write the numbers in the boxes below.Add up all the numbers. ________________________ You rolled the dice 6 times and ended up with 6 numbers so guess what you’re going to divide by? ____(If you guessed 6, great job!)Now, divide. What do you get? ________ (to the nearest tenth)-1397022606000Great job! You found the mean!Let’s try that again! This time, roll 8 dice.What do they add up to? ________________________ What do you divide by?* ________________________ 5715033655000What is the mean? ________________________ *Hint: How many dice did you roll?This time YOU get to pick how many dice to roll. Roll the dice at least 4 times and write all the numbers that show up inside the box below. What number will you divide by? How do you know?What is the mean?013335000Game Time!Find a partner who is also finished. Roll the number of dice according to the round number. (Round 5 = 5 dice) Figure out the mean. The player with the highest mean wins that round and scores one point.Round ##s you RolledThe MeanDid you win?123455495925-766445Card ValuesA = 12=23=3...10=10J=11Q=12K=13020000Card ValuesA = 12=23=3...10=10J=11Q=12K=13Median – How To…Deal 5 cards from the deck. Example: Rearrange them so they are in ascending order. (Smallest value to largest value).

You only have one card left! This is your median! What could you replace the word median with?MedianDeal out 5 new cards.

What are they? __________________________Arrange in ascending order.What problem do you see?Discuss with a partner: What ideas do you have for finding the median?You are allowed to have only one number for the median. Let’s say the two middle numbers are 8 and 12. Your median is 10. How did I figure that out?1460533845500Find the median of your cards. ________Mode…Mode…Mode…Roll the dice 6 times.How many times did the following numbers show up?Number Rolled123456Number of TimesWhich number showed up the most times? _______-381019431000That’s your mode.But Wait…What’s the mode if these were your results?Number Rolled123456Number of Times022101Did you say 2 AND 3? Excellent! You are allowed to have more than one mode.-204470244983000Roll the dice 7 times.-4318030861000What’s your mode?Roll the dice at least 4 times.-190539306500What’s the mode? _____________Game TimeFind a partner to play against. Roll 6 dice and calculate the mode. Place an x in the box that matches the mode. Player 2 goes. If the mode is already used, your turn is over. The first player to cross off all their modes…wins!123456RangeRoll the dice 4 times.Circle the largest number.Circle the smallest number. Find the difference between the largest and smallest number. _______That’s it! You found the range.-1466856413500Roll the dice 5 times.-11303035115500Find the range. ________4135844-60667600GameFind a partner. Set up the Game:Deal out 3 cards to each player.Example:Player 1 receives a 7, 4 and K (13).Player 2 receives a 2, 9 and J (11).Place the rest of the cards in between the players. Flip over the top card and place it on the side. This is your range goal. Example: 5Flip over one more card and place beside the deck. This will be your discard pile.Example: 6Play the Game:Player 1 calculates the range of their three cards. Cards 4, 7, 13Range13-4=7If Player 1’s range = Range Goal, Player 1 WINS!If not, Player 1 takes either the top card from the deck or the discard pile (Example: 6) and adds it to their hand.If they have reached the range goal, player 1 wins!If not, they must discard one card.Player 2 takes their turn.The first player to reach the range goal WINS!Mean, Mode, Median and RangeDo You Get It?Mean:How do I find the mean of the following numbers? 12, 19, 27 and 34I want to change one of those numbers so I end up with a higher mean. Which number would you change?_____What would you change it to?_____What is the new mean?_____Where might we see mean used outside of the classroom?ModePick a number. ____Create a list of 5 numbers so that the mode is your number.MedianCreate a list of 5 different numbers.Calculate the median. ________Add a 6th number so that the median is now about double the original median. What is the 6th number? ___________What is the new median? ___________RangeWrite down your own 5 numbers so that you end up with a range of 36.Where might we see range used outside of the classroom?MeanAdd up all the numbers and divide by how many numbers there were.ModeThe number that repeats the most. There can be two modes.MedianFind the middle number. If there’s two middle numbers, find the average of those two middle numbers.RangeThe difference between the highest and lowest number.Cut apart these terms and definitions. Students can be provided with these cards once they are done the other activities. Have them match them up. Can be glued into an Interactive Student Notebook. Can be used to play Concentration/Memory or fish (when added to more terms from other areas of study).-771525-8108950012477751325245WANTEDName:Alias:Guilty of:Reward: ................
