Name: _____________________________________________________Math GamesDate: ______________Rolling RatiosPlay Rolling Ratios with a partner.Rules:• Each player rolls 1 die to decide who will play first.If there is a tie, roll again.• Each partner takes a turn rolling the dice in each round.• Write the values rolled on the Recording Chart.• Write the ratio of the smaller value to the sum of the rolled values in fraction form.• 2 dice per pair of students• calculator per student• Recording Chart BLMI rolled a 2 and a 4.The sum of the rolledvalues is 2 + 4 = 6.smaller value 2=sum of values 6• Write the fraction as a decimal. Round to the nearest hundredth (2 decimal places).• Add the decimals from your turns.• The first player to reach a total of 2.5 or higher wins the game.- If both players reach 2.5 in the same round, the player with the higher total wins.- If the totals are tied, keep playing until 1 player wins.Example:Rolled Values2 and 41 and 33 and 3Ratio(fraction form)smaller value 2=sum of values 61 1=1+3 43 3=3+3 6Decimal(to the nearest hundredth)2 ÷ 6 = 0.3333…≈ 0.33Total0.331 ÷ 4 = 0.25 0.33 + 0.25 = 0.583 ÷ 6 = 0.5 0.58 + 0.5 = 1.0898 MHR ● Chapter 2: Ratios, Rates, and Proportional Reasoning
Name: _____________________________________________________Challenge in Real LifeDate: ______________Life of a Bush PilotDoug is a bush pilot.He flies medical supplies and medical workers to the Northwest Territories.You be the flight planner.Calculate the distances and times for Doug’s next trip using the map ofNorthwest Territories BLM.1. Use a ruler to measure the distances to the nearest tenth of a centimetre.Example: Hay River to Tuktoyaktuk = 7.6 cm• ruler• calculator• map of NorthwestTerritories BLMRound to 1decimal place.a) Tuktoyaktuk to Paulatuk = cm b) Paulatuk to Hay River = cm2. Use a proportion to calculate the actual flying distances.a) Hay River to Tuktoyaktuk× 7.6On the map, 1 cmrepresents 180 km.1 cm on map 7.6 cm=180 kmkm× 7.6The distance from Hay River to Tuktoyaktuk iskm.b) Tuktoyaktuk to Paulatuk c) Paulatuk to Hay RiverChallenge in Real Life ● MHR 99
