1 Functions and Tables By: Red E. Ornot

2 Our Standards Maryland VSC Standard - 1.A.1.c – Complete a function table using a one- operation (+,-,/,x) -1.A.1.d – Describe the relationship that generates a one- operation rule. Maryland Technology Literacy Student Standard (MTLSS) - 3.A.1.a Use technology tools, including software and hardware, from a range of teacher-selected options to learn new content or reinforce skills.

3 What is a Function? A function is a rule, sometimes using variables, that changes a number (input), using multiplication, division, addition, and/or subtraction creating a new number (output) Watch the introduction Movie.

4 Functions In the incomplete equation + 5 = ___, Is the input _____ is the output + 5 is the rule

5 Practice using a Function In the incomplete equation + 5 = ___, INPUT 2 into Apply the rule = ____ OUTPUT 7

6 Solving the Rule If you are given the input and the output, you must determine how the number changed using addition, subtraction, multiplication, or division. Practice using a Function 6 ______ = 9 7 ________ = 10 The rule must be + 3 because 6 + 3=9 and =

7 Sometimes we use function machines to determine rules of functions. Practice using a Function The rule of the function Input Output

8 Web practice eb/mentalmaths/functionmachines.htmlhttp://www.amblesideprimary.com/amblew eb/mentalmaths/functionmachines.html Practice using a Function

9 Function Tables InOut The input is a number going in. Lets imagine this equation + 5 = ___ The output is the result of applying the rule ( + 5) + 5 is the rule

10 Function Tables InOut Lets imagine this equation + 5 = ___ + 5 is the rule 510

11 Function Tables InOut 510 Lets imagine this equation + 5 = ___ + 5 is the rule 712

12 Function Tables InOut Lets imagine this equation + 5 = ___ + 5 is the rule 1015

13 Function Tables InOut Lets imagine this equation + 5 = ___ + 5 is the rule

14 Function Tables InOut The rule is x 3

15 Function Tables InOut The rule is -6

16 Function Tables InOut The rule is ÷4

17 Function Tables InOut The rule is + 13
