Math 9 ­ Unit 3 ­ Rational Numbers Project Name: ______________________ Class:________ Creating a Game To review for a test, Jenny and her friends are creating a game for players who know rational numbers. They decide to use a card game where you keep cards that match. They want a game with 28 cards. TASK: Create a game like Jenny’s Checklist: ❏ Did you check to make sure that you considered all the required topics? ❏ Did you explain your rules clearly? ❏ Did you explain why your matches make sense? ❏ Did you use some “creative” matches? Warm­Up: Why might the cards below match? A number between 3
− 45 and​
− 4
− 0.78 ____________________________________________ ____________________________________________ ____________________________________________ ____________________________________________ What card might match this card? ​
Explain​
why it matches. These numbers are in order: − 2 13 , − 53 , , − 1.2 ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ What pair of cards might you make to review equivalent rational numbers? (Rational Numbers that are equal) Explain why your pair works. _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ What pair of cards might you make to review Comparing and Ordering Rational Numbers? Explain why your pair works. _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ What pair of cards might you make to review Adding and Subtracting Rational Numbers? Explain why your pair works. _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ What pair of cards might you make to review Multiplying and Dividing Rational Numbers? Explain why your pair works. _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ What pair of cards might you make to review Order of Operations with Rational Numbers? Explain why your pair works. _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ Create the Cards and Rules Game Rules: _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ Cards: ● 14 Pairs (28 cards total) ● Half your cards should deal with fractions, Half with Decimals ● 2 Pairs (4 cards) for Comparing Rational Numbers ● 2 Pairs (4 cards) for Ordering Rational Numbers ● 2 Pairs (4 cards) for Adding Rational Numbers ● 2 Pairs (4 cards) for Subtracting Rational Numbers ● 2 Pairs (4 cards) for Multiplying Rational Numbers ● 2 Pairs (4 cards) for Dividing Rational Numbers ● 2 Pairs (4 cards) for Order of operations Rational Numbers Performance Assessment Rubric: Creating a Rational Numbers Game Not Represented
