If the number turned over isn't a prime number, leave the cards in the center of the table until a prime number appears and the cards are won.After a player wins cards, they must shuffle them into their deck before the game can continue.Play until one player has all the cards or set a time limit on the game and stop when time is up.The player with the most cards at the end of the game wins.Try this web site to practice making factor trees: More Factor Tree Practice  Lesson 1-3 ExponentsRace the otters to test your knowledge of exponents.Exponent JeopardyPirate Waters Exponent Board Gamehttp://www.math4childrenplus.com/exponents-pirate-game/Exponent Tic-tac-toeLesson 1-4 Order of OperationsOrder of Operations MillionaireOrder of Operations Connect 4 - with a partnerSave the seven members of the Royal Family by solving problems, step-by-step24 - Use the order of operations to form number sentences equal to 24 http://www.coolmath-games.com/0-make24/index.html Chapter 3 Games Lesson 3-1 Representing DecimalsDecimals of the Caribbean - matching the word form of decimals to the numerical formhttp://www.mrnussbaum.com/docrb.htmPlace Value PiratesFractions to Decimals PracticeLesson 3-2 Comparing and Ordering DecimalsFruit Splat  - decimal inequalitiesBalloon Pop Lesson 3-3 Rounding Decimals Scooter QuestSoccer Math Lesson 3-4 Estimating Sums & Differences of DecimalsPractice Problems Lesson 3-5  Sums & Differences of DecimalsMatch problems and answersFind the right hotel room for each owl by matching problems and answersDecimal Subtraction Baseball Lesson 3-6 and 3-7 Multiplying DecimalsSnakes and Ladders  Lesson 3-8 and 3-9 Dividing Decimals Practice Solving Word Problems (scratch pad available) Decimal Football (you will need a scratch pad)Step-by-step division practice (whole #s only) Chapter 4 GamesLesson 4-1 Greatest Common Factor (GCF)Fruit SplatHelp Sketch Complete Each level Lesson 4-2 Simplifying FractionsHelp the Math Man Monster eat all of the dots and find the correct simplified fraction Reducing Fraction PracticeBINGOhttp://www.abcya.com/equivalent_fractions_bingo.htmFraction Frenzy - match equivalent fractionshttp://www.learningplanet.com/sam/ff/index.asp Lesson 4-3 Mixed Numbers and Improper FractionsConverting PracticeTimed Practice - play to beat your last time Lesson 4-5 Least Common Multiple (LCM) Snowball FightPlay Common Denominator War with a partnerWrite numbers on at least 20 index cards, making sure that most of the numbers are not prime. For example, you might choose numbers such as 8 (which has the factors 2 and 4) or 9 (which has 3 as a factor) more often than 7 or 11, which are both prime. Most of the numbers should be between 1 and 20, with a few larger ones that have a lot of factors (e.g., 20, 24, 30).Divide the pile of index cards in half into two smaller piles, and give each player one of these smaller piles.Both players call out “1, 2, 3…war!” and simultaneously turn over the top card in their piles and place it between them.The goal: as quickly as each player can, calculate the lowest common multiple of the numbers on the two cards, and call it out.The first player to call out the correct lowest common multiple wins the round and gets to add both of the cards to the bottom of her pile. Repeat Steps 3 and 4 for the next round.The game ends when one player runs out of cards. The other player is the winner.Lesson 4-6 Comparing & Ordering FractionsPracticeTug TeamOrder Fractions by popping balloons in the correct order Lesson 4-7 and 4-8 Converting Decimals and Fractions Chapter 5 GamesLesson 5-1 Rounding FractionsMATHMANhttp://www.sheppardsoftware.com/mathgames/fractions/mathman_round_mixed_numbers.htmIdentifying Fractions on a Number LineFind GrampyFind Grampy (more difficult)Lesson 5-3 and 5-4 Adding & Subtracting Fractions Fruit Splat https://www.sheppardsoftware.com/mathgames/fractions/FruitShootFractionsAddition.htmLesson 5-5 Adding & Subtracting Mixed NumbersAdding PracticeSubtracting PracticeLesson 5-6 Estimating ProductsPracticeLesson 5-7 Multiplying FractionsSnowsled RaceLesson 5-8 Multiplying Mixed NumbersPractice with scratchpadLesson 5-9 Dividing FractionsPiratesDivide using fraction modelsLesson 5-10 Dividing Mixed Numbers
