ALCOS Standard: Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols. [5-OA1]
Students are able to:
Efficiently apply strategies for rewriting and evaluating expressions that contain parentheses, brackets, and/or braces.
M. 5.1.3: Recognize expressions
M. 5.1.4: Apply properties of operations as strategies to add and subtract.
M. 5.1.5: Recall properties of operations as strategies to add and subtract.
M. 5.1.6: Represent addition and subtraction with objects, mental images, drawings, expressions, or equations.
Essential Question(s): How can you use properties of operations to solve problems?
Lesson Focus: Daily Data: Evaluate the following expression ( 13 + 9 + 7 ) and list steps used to solve the expression on a graphic organizer. How would you find the sum? Would it be easier to add 13 and 9 and then add 7, or would it be easier to add 13 and 7 and then add 9? Explain. Students will share their steps with the class. The class will have an open ended discussion of how to solve the expression. Students will continue with this concept as part of the class’s daily data tomorrow.
Vocabulary Practice: Match the words with the correct definition handout using textbook pages 13 and 14 : Distributive Property, Commutative Property of Addition, Associative Property of Addition, Identity Property of Addition, Commutative Property of Multiplication, Associative Property of Multiplication, Identity Property of Multiplication
Guided Practice (I Do, You Do, And We Do Method): I do: Students watch as I solve problems using the associative, commutative, identity, and distributive property. We do: Students complete textbook examples on pages 13 and 14. You do: Students practice properties through completing examples 5, 6, 10, and 11 on textbook page 15.
