Vocab Multiplicative Identity A number multiplied by 1 is that number Multiplicative Inverse A number multiplied by its reciprocal is 1 Quotient I s the answer for division problemsDividend NumeratorDivisor Denominator
Investigation 3: Multiplying and Dividing Rational Numbers Students will demonstrate how to combine numbers with the same sign and different signs
3.1 Multiplication Patterns with Integers Students will solve multiplication problems using properties of muliplication .
Problem 3.1 pg 56 Video Look over first page of 3.1 after video we will discuss the questions at the bottom of the page Work through A only in the investigation What is multiplication Repeated addition What are some of the basic multiplication rules/facts that you know? Think of a table that you consistently add or subtractHow do you represent multiplication? (symbols/words) times, product, doubleHow would you represent multiplication on a number line, a chip board?How does this prove two negative signs in a row turns into a positive
3.2 Multiplication of Rational Numbers Students will be able to solve multiplication of rational numbers using properties discussed in previous section.
Problem 3.2 pg 58 Do A 1 and 2 What is common ? Similar numbers, signs different, answers are opposties What is the product for each?Do C 1 – 3 Rules for 2 pos, 2 neg, 1 of each, previously discussedDo E Predict if answer is Pos or Neg don’t actually solve, but be able to explain why Rules for signs and multiplication Even number of neg and answer is pos Odd number of neg and answers is neg How do we multiply fractions Num to Num and Denom to denom How do we multiply mixed numbers Convert to improper and multiple How do we multiply if more than one multiplication Does order matter
Warm-up Discuss problem 41 on homework
3.3 Division of Rational Numbers Students will solve division problems using properties of division.
Problem 3.3 start on Page 60 Read page 60 and answer question at bottom of page . How does a fact family prove 15/0 = a cannot be True? Do B (remember what a rate is), be able to explain your process Do C 1,2 and 4 Do E Do FDo GWe will discuss in classWhat is division Undoing multiplication, breaking apart a numberHow do we divide numbers – how many times a number goes into another numberHow do we divide fractions KFCWhat is we have negatives Triangle
3.4 Playing the Integer Product Game Students will play a game to help with their multiplication and division skills
Integer Product Game pg 64 2 players game, we may need some groups of 3 Then on page 65 answer A and E We will discuss as a class Discuss Homework Due Problem 41
Quiz Review Items Multiplication and Division are key concepts Can you rewrite expression to solve for a variable, fact families Multiplicative Identity and Inverse Algorithms to help with solving Writing number sentences or equations
Warm-up Find area and perimeter
