If...Then? Today I can construct function tables with if...then statements using simple equations.
Essential Questions What is mathematical reasoning? How does it relate to if...then statements? What is an algebraic function? What are the rules of computation?
Think...what operations do we use in math? List as many as you can on your whiteboard. Share with your face partner. Discuss as a class. For starters....
I have a PS3 and have 12 games next to the machine. If I had 20 games total then how many am I missing? What operation is this problem? How did you come to that conclusion?
Vocabulary Mathematical reasoning: Thinking through math problems logically in order to arrive at solutions. Algebraic function: A function involving addition, subtraction, multiplication, and/or division to solve a problem such as finding what X is.
Order of Operations Parenthesis Exponents Multiplication Division Addition Subtraction Please Excuse My Dear Aunt Sally!
Mathematical Symbols Multiplication: x ( ) Division: ÷ / 4x3 or 4(3) or ÷5 or 30/5..
Lets try a few using PEMDAS! 2(3) + 4(7) = 2(3+2) = 30/5 - 4(1) =
Now on your own... (3+11) + (34-16) = 7(8) - 54 = 144/ = Dont forget PEMDAS!
If...then statements 4 x A = B If...A = 5 then...B = ? 4 x 5 = ?
Try one! 25 + X = Y If... X = 13 then...Y =? = 38 Y = 38
Function Tables XY X=Y If I were to continue this table...using mathematical reasoning...what would come next? How did you come to that conclusion? If X is 2...then Y is...
Lets try one together! XY 3X+6=Y Dont forget PEMDAS!
On your own complete the function table.AB (A+3)2=B Dont forget PEMDAS!
Closure What are the rules for computation? (Order of Operations) How do if...then statements help me to complete a function table? Share...in your table groups share your summary. Share...with me!
