Unit 3 Multiplication & Division Parent Preview

Multiplication Facts  Students will be timed on their multiplication facts On Grade students must master their 0-10 facts Above Grade students must master 0-12 facts.

Multiplication Strategies  Groups of: 3 groups of 4 = 12  Repeated Addition: Add 3 Four separate times = = = 12

Multiplication Strategies Continued  Arrays: 3 x 5 (down x across) x x x x x  Number Lines: (see next slide)

Number Line Multiplication Spaces x Jumps 5 x

Division Strategies  Groups of: 21 ÷ 3 = 5  Repeated Subtraction: 21 ÷ 3

Fact Families 48 6 x ÷ ______ x _______________ ÷ ________ _____ x ________________ ÷ ________

Comparison Multiplication  Students will be able represent multiplication through pictures Sally Kelly Sally has ____ times as many pandas as Kelly does.

Multiplication & Division Word Problems  Students must be able to write their own multiplication word problem Ex: Karen has 5 oranges. Jeff has 2 times as many oranges as Karen does. How many oranges does Jeff have?

Multiplication & Division Word Problems Continued…  When given a word problem students will need to evaluate the problem to determine if they need to multiply or divide. Ex Multiplication: There are 5 trees in Susan’s backyard. There are 4 birds sitting on each tree. How many total birds are there? Ex Division: Jason has 40 baseball cards and 8 shoeboxes. He wants to put an even number of cards in each box. How many cards will go in each box?

Commutative Property If number sentence is reversed you will always have the same answer  ( = 7 OR = 7……5 x 6 = 30 OR 6 x 5 = 30)

Commutative Property  If an addition/multiplication number sentence is reversed the sum/product will remain the same Example: = 7 OR = 7 Example: 4 x 3 = 12 OR 3 x 4 = 12

Factors and Multiples  Factor – numbers that multiply together to get a product Factors of 10 are: 1, 10, 5, 2  Multiple – Product of a number x number Multiples of 10 are: 10, 20, 30, 40, 50, etc.

Solving for the Unknown  The unknown will be represented by a letter (ex: x, y, p) 46 + p = 50  p = 4  Function Tables Rule: y = x + 5 XY

Solving for the Unknown Word Problem  Jason has 25 toy cars. He adds in some toy trucks. He now has a total of 52 toys.  Students will have to identify… What 25 represents What 52 represents What the unknown is  Students will have to… Create an equation Solve for the unknown
