1
Multiplication In the second quarter, students will multiply using various strategies.

2
Strategies: repeated addition equal groups arrays skip-counting commutative property associative property distributive property

3
Repeated Addition Students will understand that 4 x 3 can be solved by using repeated addition. Example: 4 + 4 + 4

4
Equal Groups Students will understand that 4 x 3 can be solved by creating equal groups. Example:

5
Arrays An array is a group of objects arranged in rows and columns. Students will know how to identify and create arrays to solve multiplication problems. Example 3 rows with 4 in each row = 3 x 4 = 12

6
Skip Counting Students will use skip-counting to solve multiplication problems. Example: 3 x 4 369121518242730

7
Commutative Property Students will be able to demonstrate the commutative property by writing related equations. Example 4 x 3 = 12 3 x 4 =12

8
Associative Property Students will be able to use the associative property to solve equations with more than 2 factors. Students will know that it doesn’t matter which order you multiply, your answer will remain the same. Example: 2 x 3 x 5 = 30 2 x 3 6 x 5 = 30 Or 3 x 5 15 x 2 =30 Or 2 x 5 10 x 3 = 30

9
Distributive Property Students will be able to apply the distributive property to solve multiplication problems. Example: 8 x 7 = 56 can be solved by breaking apart the 7 into 2 addends (2 + 5) and then multiplying 8 by each addend: 8 x 2 = 16 8 x 5 = 40 16 + 40 = 56

10
Multiplication Facts Students will also be expected to memorize their multiplication facts. We will practice our facts by: Playing games Using flash cards Online resources such as sumdog.com, etc. Weekly timed tests these will start in November these will not be recorded as a grade; they are just for practice
