Math Chapter 2-1 Multiplication Properties Standard: Algebra and Functions 1.3: Apply and commutative, associative, and distributive properties; and justify each step in the process. Mathematical Reasoning 3.3: Develop generalizations of the results and the strategies used and apply them in the new problem. Content Objective: We will use multiplication properties and mental math strategies to compute mentally. Language Objective: We will read, write and discuss the lesson and work together to practice the concepts.

4
The order in which numbers are multiplied does not affect the product. 5 (20) = 20 (5) The way in which factors are grouped does not affect the product. 3 x (2 x 5) = (3 x 2) x 5 The product of one and any number is that number. 45 (1) = 45 Commutative Property Associative Property Identity Property

5
Property of Zero Distributive Property Added The product of zero and any number is zero. 9,999 (0) = 0 Multiplying a factor by a group of addends yields the same result as multiplying that factor by each addend and then adding the products. 6 x (5 + 4) = 6 (5) + 6 (4) number to be added: a number that is to be added

Math Chapter 2-4 Dividing Whole Number Standard: Number Sense 2.2: Demonstrate proficiency with division, including division with long division with multi-digit divisors. Mathematical Reasoning 2.7: Check your results from the context of the problem. Content Objective: We will divide whole numbers and decimals by whole numbers. Language Objective: We will read, write and discuss the lesson and work together to practice the concepts.

17
Use your estimate to help you place the first digit in the quotient. Divide the hundreds. Divide 26/23 Multiply 23(1) Subtract 26-23 Compare 3<23 Divide the tens. Bring down Divide 32/23 Multiply 23(1) Subtract 32-23 Compare 9<23 Divide the ones. Bring down Divide 92/23 Multiply 23(4) Subtract 92-92 Step 1: Example: 23/ 2,622 Step 2: Step 3: Write the remainder, if any, in the quotient.

Math Chapter 2-7 Solving Multiplication and Division Equations Standard: Algebra and Functions 1.1: Write and solve one-step linear equations in one variable. Content Objective: We will solve multiplication and division equations. Language Objective: We will read, write and discuss the lesson and work together to practice the concepts.

31
Multiplication and division are inverse operations. Use division to “undo” multiplication. Use multiplication to “undo” division. To undo dividing multiply BOTH sides by the same number. a =58 11 a x 11 = 58 x11 11 Since 11/11 = 1 a is by itself on one side of the equal sign. a = 58(11) Solve for the variable a a=638 To undo multiplication, divide BOTH sides by the same number. 6z = 114 6 6 Isolate the unknown variable by dividing both sides by 6. (or the number next to the unknown variable) z=114/6 Solve for the variable z z= 19
