OBJECTIVES:
Students will:
*write multiplication number sentences for given equal group situations using the x symbol.
*write multiplication sentences for arrays and use arrays to find products.
*write multiplication sentences for arrays, use arrays to find products, and use the Commutative Property of Multiplication
Vocabulary Terms:
Equal Groups: have the same number of items in each group
Equation: A number sentence that uses an equal sign (=) to show the value to its left is the same as the value to its right
Unknown: a symbol or letter that stands for a number in an equation
Row: objects that are arranged in a line across
Column: an arrangement of objects or numbers one above another
Multiplication: An operation that gives the total number when you join equal groups.
Factors: Numbers that are multiplied to give a product.
Example: 3 x 8 = 24
The factors are 3 and 8
Product: The answer to a multiplication problem.
Example: 3 x 8 = 24
The product is 24
Array: A way of displaying objects in equal rows
Example:
xxxx
xxxx This is an array of 2 x 4
Commutative (Order) Property of Multiplication: Numbers that can be multiplied in any order and the product will be the same.
Example: 4 x 3 = 3 x 4
Division: an operation that tells how many equal groups there are or how many in each group.
Topic 2 Multiplication Facts: Use Patterns
Pearson Realize Website
Objectives:
Students will:
*Gain fluency in multiplication when using 2, 5, and 9 as a factor
*Gain fluency in multiplication when multiplying by 0, 1 or 10 as a factor
*Students will use number relationships and patterns to develop reasoning strategies to support their recall of the basic multiplication facts
*Use previously learned concepts and skills to represent and solve problems
Vocabulary
Multiples:
The products of a whole number and other whole numbers.
Example: 5, 10, 15, 20 are some multiples of 5.
Identity (One) Property of Multiplication:
The product of any number and 1 is that number.
Example: 8 x 1 = 8
Zero Property of Multiplication:
The product of any number and zero is zero.
Example: 4 x 0 = 0
Topic 3
Apply Properties: Multiplication Facts for 3, 4, 6, 7, 8
Pearson Realize Website
Objectives:
Use the distributive property to solve problems involving multiplication to 100
Use the distributive property to break apart unknown facts with 3, 4, 6, 7, or 8 as a factor
Use strategies such as bar diagrams and arrays with known facts to solve problems with multiplication
Use the Associative Property of Multiplication to group factors when multiplying 3 factors
Use repeated reasoning with known facts to make generalizations when multiplying
Vocabulary:
Distributive Property: A multiplication fact can be broken apart into the sum of two other multiplication facts. 5x6 = (5x3) + (5x3)
4x7= (4x3) + (4x4)
Associative (Grouping) Property of Multiplication: The grouping of factors can be changed and the product will be the same.
(2x3) x 5 = 30, 2 x (3x5) = 30
